HMC7911LP5ETR

The HMC7911LP5ETR is a compact gallium arsenide (GaAs), pseudo-morphic (pHEMT), monolithic microwave integrated circuit (MMIC) upconverter from Analog Devices. It operates within a frequency range of 17.0 GHz to 20.0 GHz, providing a small signal conversion gain of 18 dB typical and 30 dBc typical sideband rejection.

This device features an input power for 1 dB compression (P1dB) of 2 dBm typical and an output third-order intercept (OIP3) of 33 dBm typical. It also includes local oscillator (LO) leakage specifications, with 10 dBm typical at RFOUT and -25 dBm typical at the IF input. The RF return loss is 13 dB typical, and the LO return loss is 10 dB typical.

The HMC7911LP5ETR is housed in a 32-lead, 5 mm × 5 mm LFCSP package, suitable for surface mount applications. Its design utilizes an I/Q mixer topology driven by an active 2× local oscillator multiplier, reducing the need for extensive filtering of unwanted sidebands. This makes it a smaller alternative to traditional single sideband upconverter assemblies and compatible with surface-mount manufacturing techniques.

Applications for this upconverter include point-to-point and point-to-multipoint radios, military radars, electronic warfare (EW), electronic intelligence (ELINT), and satellite communications.
