Wideband Amplifier Chip, 0.5 - 80 GHz

The HMC-AUH312 is a gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), HEMT, low noise, wideband amplifier die that operates between 500 MHz and 80 GHz, providing a typical 3 dB bandwidth of 80 GHz. The amplifier provides 10 dB of small signal gain and a maximum output amplitude of 2.5 V p-p, which makes it ideal for use in broadband wireless, fiber optic communications, and test equipment applications.

The amplifier die occupies 1.2 mm × 1.0 mm, facilitating easy integration into a multichip module (MCM). The HMC-AUH312 can be used with or without a bias tee, and requires off-chip blocking components and bypass capacitors for the dc supply lines. Adjustable gate voltages allow for gain adjustment.
