HMC576 18–29GHz ×2 Active Frequency Multiplier Die
Manufacturer: Analog Devices / Hittite Microwave
Product Type: GaAs pHEMT MMIC ×2 Active Frequency Multiplier
Input Frequency Range: 9GHz to 14.5GHzOutput Frequency Range: 18GHz to 29GHz
Package: Bare Die
Description: 18–29GHz output GaAs pHEMT MMIC ×2 active frequency multiplier die with +17dBm typical output power, -132dBc/Hz additive phase noise and single +5V operation.
The HMC576 is a broadband ×2 active frequency multiplier die for microwave local oscillator and high-frequency signal-generation chains. It accepts a 9–14.5GHz input and generates an 18–29GHz output.
The integrated GaAs pHEMT architecture combines frequency multiplication and output amplification in one compact die. It can reduce the number of multiplier and buffer stages required in point-to-point radio, VSAT, radar, electronic warfare and microwave test equipment.

Typical Applications
Microwave Local Oscillator Chains
HMC576 can generate an 18–29GHz LO signal from a lower-frequency microwave source. Its active architecture reduces the number of separate multiplication and amplification stages required in the signal chain.
Point-to-Point Microwave Radio
The device is suitable for microwave radio transceivers operating in upper microwave bands. Its output level may be sufficient to drive a following mixer or LO-distribution stage, depending on the required input power.
VSAT and Satellite Communication
HMC576 supports local oscillator generation in VSAT terminals, satellite communication modules and frequency-conversion assemblies operating across K- and lower Ka-band frequencies.
Military Radar and Electronic Warfare
The broad frequency range and low additive phase noise make HMC576 suitable for radar sources, electronic warfare equipment and frequency-agile microwave assemblies.
Space Systems
The compact bare-die format supports integration into hybrid and multichip microwave modules used in space communication and sensing equipment. Screening, qualification and traceability requirements must be specified separately.
Test and Measurement
HMC576 can be used in microwave signal generators, frequency extenders, source modules and laboratory test equipment requiring an 18–29GHz output.
HMC576 Related Models
HMC561 covers a lower 8–21GHz output range, while HMC578 extends ×2 multiplication to approximately 24–33GHz. These models serve different frequency bands and are not direct drop-in replacements for HMC576.
