HMC445LP4E 9.9–11.2GHz ×16 Active Frequency Multiplier
Manufacturer: Analog Devices / Hittite Microwave
Product Type: InGaP GaAs HBT ×16 Active Frequency Multiplier
Output Frequency Range: 9.9GHz to 11.2GHzPackage: 24-Lead QFN, 4mm × 4mm with Exposed Pad
Description: 9.9–11.2GHz ×16 active frequency multiplier with +7dBm typical output power, low additive phase noise and greater than 25dBc subharmonic suppression for X-band LO generation.
The HMC445LP4E is a compact ×16 active frequency multiplier designed to generate X-band local oscillator signals from a lower-frequency input. It combines multiple multiplication stages in one surface-mount device, reducing the number of discrete multipliers, amplifiers and filters required in a conventional LO chain.
Output power remains relatively stable against changes in input power, temperature and supply voltage. The device is suitable for microwave systems that require a compact frequency-multiplication stage with controlled output power and low additive phase noise.

Typical Applications
X-Band Local Oscillator Generation
HMC445LP4E can generate a 9.9–11.2GHz LO signal from a much lower-frequency source. This reduces the number of separate multiplier and amplifier stages required in an X-band frequency-generation chain.
Point-to-Point Microwave Radio
The device is suitable for microwave radio transceivers requiring a compact and stable LO multiplier stage. Its integrated architecture helps reduce component count and occupied PCB area.
Military Radar
HMC445LP4E can be used in X-band radar frequency-generation circuits where low additive phase noise and subharmonic suppression are important to system performance.
Fiber-Optic Equipment
The multiplier can support high-frequency clock and signal-generation functions in fiber-optic communication and test equipment.
Microwave Test Systems
HMC445LP4E is also suitable for signal generators, frequency-extension assemblies and laboratory microwave sources operating near 10GHz.
