Who we are
HopFreq is the brand of Chengdu HopFreq Electronic Technology Co., Ltd. Founded in 2008, we employ 180 people — 60 of them RF, microwave, mechanical and test engineers — in a 12 000 m² facility combining an MMIC design centre, a hybrid microelectronics line and a fully instrumented test laboratory.
What we do
We focus on two product families: frequency sources and T/R modules. Frequency synthesis, phase-locked loops, power amplification, filtering and switching are designed with the same in-house toolchain, so the phase-noise budget of a source and the noise figure of a T/R module are optimised together instead of being traded off between vendors.
- Frequency sources from DC to 40 GHz — comb generators, compact low-phase-noise sources, phase-locked sources, broadband SiP sources and synthesizer modules
- T/R modules in L, X and Ku band — single-transmit / multi-receive architectures with integrated fast-hopping synthesis
- MMIC and RFIC design on GaAs, GaN-on-SiC and CMOS-SOI; hybrid and multilayer LTCC module integration
- Automated RF test, temperature cycling, vibration and burn-in screening
Quality
Every production lot passes incoming inspection, in-process RF test, 168-hour burn-in and final screening. Full measured data and typical performance curves are supplied with each delivery so that batch consistency can be verified.
