Product Description
UMS CHX and CHU series MMIC frequency multipliers provide output-frequency coverage from 16 to 77 GHz. Available multiplication ratios include X2, X3, X4 and X6, supporting microwave and millimeter-wave local oscillator generation in communication, radar and frequency-conversion systems.
The CHX series includes cascadable frequency doublers, triplers and quadruplers in Die or QFN packages. The CHU2277 and CHU3377 are multifunction W-band devices integrating frequency multiplication and amplification for 76–77 GHz radar applications.

Selection and Applications
For output frequencies below 26 GHz, CHX2089-99F and the CHX2090 family provide X2 multiplication for Ku-, K- and lower Ka-band LO chains. The CHX2090-99F is supplied as a Die, while CHX2090-QDG offers a packaged SMD alternative.
For 33–43.5 GHz output generation, designers can select CHX1191-98F/QDG, CHX1162-QDG, CHX2091-99F or CHX2092a99F according to the required input band and multiplication ratio. CHX1162-QDG and CHX1191-QDG integrate buffers in standard surface-mount packages and are intended for communication and E-band LO-chain designs.
For 76–77 GHz automotive and industrial radar, CHU2277-99F/CHU2277a98F accept a 38 GHz input and provide X2 multiplication. CHU3377-98F uses an overall X6 architecture, allowing a lower 12.67–12.83 GHz input signal.
Frequently Asked Questions
Q1: Which UMS multipliers provide a 76–77 GHz output?
The CHU2277-99F, CHU2277a98F and CHU3377-98F are designed for 76–77 GHz W-band output generation.
Q2: What is the difference between CHU2277 and CHU3377?
CHU2277 is an X2 multiplier using a 38–38.5 GHz input, while CHU3377 provides X6 multiplication from a 12.67–12.83 GHz input. CHU3377 also provides a higher nominal output power of 15 dBm.
Q3: Which models are available in QFN packages?
The packaged options shown here are CHX1162-QDG, CHX1191-QDG and CHX2090-QDG. The remaining models are supplied as bare Die.
Q4: What is the difference between CHX2090-99F and CHX2090-QDG?
Both are X2 multipliers covering an 11–13 GHz input and 22–26 GHz output. CHX2090-99F is a Die with 15 dBm output power, while CHX2090-QDG is a QFN device with 12 dBm output power.
Q5: Which models are suitable for 33–43.5 GHz LO generation?
The CHX1191-98F and CHX1191-QDG provide X3 multiplication, while CHX1162-QDG provides X2 multiplication. The choice depends primarily on the available input frequency and package requirement.
