HMC-AUH312-DIE Series

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.ApplicationsFiber optic modulator driversFiber optic photoreceiver postamplifiersLow noise amplifier for test and measurement equipmentPoint to point and point to multipoint radiosWideband communication and surveillance systemsRadar warning receivers
