W-Band FMCW Transceiver Module 92-96GHz

Huashi W-Band FMCW Transceiver Module

92-96 GHz · +18 dBm Output · X8 Frequency Multiplier · 4 dB NF · 20 dB Gain · DC-1 GHz IF · WR-10 Waveguide

Independently developed, manufactured and supplied by Shenzhen Huashi Digital Technology Co., Ltd., this W-band FMCW transceiver module provides a complete transmit-and-receive chain for millimeter-wave radar, satellite communication payloads and broadband RF systems. It integrates an X8-multiplier transmit channel and a homodyne I/Q receive channel in one module ready for direct system integration.

Key Features

· Built-in X8 frequency multiplier on transmit: 11.5-12 GHz input (+3 dBm typical) converted directly to 92-96 GHz output - no W-band LO source required;

· Output power +18 dBm (min. +17 dBm) with 7th/9th harmonic suppression typically -35 dBc for a clean spectrum;

· Receive noise figure 4 dB, RF-to-IF gain 20 dB, I/Q amplitude balance ±2 dB and phase balance ±5°, giving better than 20 dB image rejection;

· DC-1 GHz IF bandwidth supports up to 4 GHz-class FMCW modulation, enabling range resolution on the order of 3.75 cm;

· Shared LO between TX and RX ensures coherent FMCW operation for clean range-Doppler processing;

· WR-10 waveguide RF port, SMA IF/IQ ports and J30J micro-rectangular power connector for easy system integration;

· Temperature-compensated operation from -10 to +50 °C; excellent unit-to-unit consistency (output-power spread tightened to ±0.5 dB in volume production).

Main Specifications

Engineering Capability: From Prototype to Volume Production

With 30 years of RF industry experience, Huashi covers the full engineering cycle of W-band assemblies: requirement breakdown and link-budget analysis, GaN/GaAs MMIC selection with load-pull-based matching, waveguide transitions and precision-machined housings (±0.01 mm tolerance), gold-wire bonding (0.3-0.5 mm double-wire process), automatic bias sequencing, ATE-based production testing and full data traceability. In volume production, die binning, reserved tuning pads and gate-voltage calibration stored in EEPROM tighten batch output-power spread from ±2 dB to ±0.5 dB.

Typical Applications

· W-band FMCW radar: counter-UAS detection radar and high-resolution imaging radar (4 GHz bandwidth = 3.75 cm range resolution);

· Satellite communication payloads and LEO ground terminals: broadband transceiver front ends and V/E-band system prototyping;

· Millimeter-wave test and measurement: W-band frequency-extender front ends for spurious and phase-noise measurements;

· Counter-UAS jammer payloads: scalable to +28 dBm or higher combined output with power-combining architectures.

Supply and Customization

The module is independently developed, manufactured and supplied by Shenzhen Huashi Digital Technology Co., Ltd. Custom frequency bands, bandwidth, output power, interfaces and mechanical designs are supported. Volume shipments come with batch-consistency reports and traceability documentation. E-band and other RF-band products are also available on request.
