Communications Infrastructure RF Solution
Modern communications infrastructure — 5G base stations, SATCOM ground terminals, military tactical radio systems — depends on a small number of high-performance RF transceiver and clock distribution ICs. The Analog Devices AD9371 (transceiver) and Hittite HMC7043 (clock distribution) are the industry reference designs for these applications. Both are subject to US Export Administration Regulations.
Radivix Technology supplies export-compliant alternatives distributed from Hong Kong: RVX2204MPB (AD9371 replacement) and RVX01AME (HMC7043 replacement), complemented by RVX02ME for low-power clock applications (CDCM6208 alternative). Together they provide a complete, US-restriction-free RF chain for communications infrastructure designers.
Summary: Radivix provides three export-compliant ICs covering the complete communications infrastructure RF stack — wideband transceiver (RVX2204MPB), high-performance clock distribution (RVX01AME), and low-power clock synthesis (RVX02ME). All three are available from Hong Kong without US EAR or ITAR exposure, directly replacing the Analog Devices/Hittite reference stack used in 5G, SATCOM, and tactical communications hardware.
RVX2204MPB — AD9371 Alternative: Wideband RF Transceiver
The RVX2204MPB is a wideband RF transceiver IC covering 300 MHz to 6 GHz with up to 100 MHz instantaneous bandwidth per channel. It implements a direct-conversion architecture with integrated synthesizer, independent transmit and receive paths, and a JESD204B high-speed digital interface — the same architectural profile as the Analog Devices AD9371.
The 100 MHz channel bandwidth supports all major carrier configurations in LTE and 5G NR FR1 (sub-6 GHz), including 20 MHz LTE, 100 MHz 5G NR component carriers, and 100 MHz SATCOM transponder channels. The JESD204B interface enables direct connection to high-speed FPGA transceivers for baseband signal processing.

JESD204B Digital Interface
RVX2204MPB outputs I/Q samples over JESD204B lanes, directly interfacing with modern FPGAs (Xilinx/AMD, Intel/Altera) that implement the JESD204B IP core. Lane count and serialization factor are configurable, allowing the designer to trade link rate against lane count according to FPGA I/O availability. SYSREF input accepts distributed timing from RVX01AME for multi-transceiver synchronization.
Migration note: RVX2204MPB shares the BGA196 footprint with AD9371. A pin-delta document covering power rail assignments and JESD204B differential pair routing is included in the datasheet package. JESD204B ILAS (Initial Lane Alignment Sequence) and SYSREF timing requirements are functionally equivalent.
Summary: RVX2204MPB matches the AD9371 across the critical parameters for 5G, SATCOM, and tactical communications design — 300 MHz–6 GHz tuning, 100 MHz bandwidth, JESD204B interface, BGA196 footprint. It delivers a fully export-compliant transceiver from Hong Kong, eliminating US-origin supply risk for infrastructure programs operating outside US export control exemptions.
RVX01AME — HMC7043 Alternative: 3.2 GHz Clock Distribution
The RVX01AME replaces the Hittite HMC7043 as the multi-output low-jitter clock distribution IC in communications infrastructure designs. It accepts a reference input up to 3.2 GHz and distributes it across 14 independently configurable output channels with sub-picosecond channel-to-channel jitter.
In a 5G base station, RVX01AME distributes sample clocks and SYSREF pulses from a single board-level oscillator to multiple RVX2204MPB transceivers, ADC/DAC chains, and the FPGA clock network. SYSREF generation in JESD204B subclass 1 mode ensures deterministic latency alignment between all transceivers and the digital back-end, critical for multi-antenna MIMO and beamforming operation.
Key Specifications

|---|---|---|
| Max Input Frequency | 3.2 GHz | 3.2 GHz |
| Output Channels | 14 | 14 |

Summary: RVX01AME provides 14 phase-aligned, sub-ps jitter clock outputs from a single 3.2 GHz reference — identical to HMC7043 in channel count, output formats, and JESD204B SYSREF capability. In a 5G or SATCOM multi-transceiver design, it ensures all RVX2204MPB devices and FPGA JESD204B cores share a deterministically-aligned sample clock, with no US-origin component exposure.
RVX02ME — CDCM6208 Alternative: Low-Power Clock Solution
For compact small cell and SATCOM terminal designs where power budget is constrained, the RVX02ME provides clock synthesis and distribution at a 1.2 W power budget — significantly below the RVX01AME in applications where 14 outputs are not required.
RVX02ME replaces the Texas Instruments CDCM6208 (also subject to US EAR) in designs requiring a moderate channel-count clock tree with minimal thermal burden. It suits compact outdoor small cell units, man-portable SATCOM terminals, and handheld tactical communications hardware where board space and cooling are constrained.
Key Specifications
| Parameter | RVX02ME | CDCM6208 (reference) |
|---|---|---|
| Power Consumption | ~1.2 W | ~1.2 W |
| Output Channels | 8 | 8 |
| Output Formats | LVDS / LVCMOS | LVDS / LVCMOS |
| Phase Noise | Low (spec in datasheet) | Low |
| Export Status | ✅ HK — No EAR/ITAR | ⚠️ US-controlled |
Summary: RVX02ME delivers CDCM6208-equivalent clock synthesis at 1.2 W — enabling export-compliant clock distribution in power-sensitive designs such as outdoor small cells, portable SATCOM terminals, and compact tactical radio units. It completes the Radivix clock portfolio by covering lower-output-count, power-constrained applications not served by the full 14-output RVX01AME.
Applications
RVX2204MPB covers all 5G NR FR1 bands. RVX01AME or RVX02ME provides JESD204B-compliant clocking for multi-transceiver small cell units in dense urban deployments.
300 MHz–6 GHz coverage spans L/S/C/X-band SATCOM downlink channels. RVX2204MPB's 100 MHz bandwidth supports broadband SATCOM carriers including Ku-band after downconversion.
Frequency-hopping and software-reconfigurable tactical radios require wide tuning range and rapid reconfiguration. RVX2204MPB's SPI-controlled LO supports fast frequency agility across VHF through SHF.
Multi-sector macro cells require multiple transceivers with phase-coherent clocking. RVX01AME's 14-output SYSREF distribution enables JESD204B subclass 1 synchronization across all sectors in a base station chassis.
5G NR Band Coverage
The 300 MHz–6 GHz tuning range of RVX2204MPB covers the following 5G NR frequency bands defined by 3GPP:
- n1 (2100 MHz), n3 (1800 MHz), n7 (2600 MHz) — mainstream FDD bands
- n28 (700 MHz) — wide-area coverage
- n40 (2300 MHz), n41 (2500 MHz) — TD-LTE/5G NR TDD
- n77 (3.3–4.2 GHz), n78 (3.3–3.8 GHz) — primary 5G mid-band
- n79 (4.4–5.0 GHz) — high-density urban 5G
Summary: RVX2204MPB + RVX01AME covers the complete 5G NR FR1 band plan, SATCOM L/S/C-band downlinks, and tactical VHF/UHF/SHF radio requirements in a single, export-compliant IC pair. Programs deploying communications infrastructure across the Middle East, CIS, and Southeast Asia can replace the AD9371 + HMC7043 reference stack without modification to board topology.
