CHA5014-99F

The CHA5014-99F from United Monolithic Semiconductors is a Two-Stage GaAs Power Amplifier that operates from 8.5 to 11 GHz. This driver amplifier is designed for systems that require an output power that is weakly sensitive to temperature, and it includes a special control circuit that stabilizes the output power with respect to temperature. It delivers a saturated output power of 1 W (~30 dBm) with a small signal gain of 20 dB and a power added efficiency of 35%. This two-stage driver amplifier has an input and output return loss of -12 dB. 

The CHA5014-99F  is manufactured using a GaInP HBT process, including via holes through the substrate & air bridges, and has a nitride layer that protects the transistors & the passive components. This MMIC amplifier requires a DC supply of 8.5 V and consumes less than 260 mA of current. It has two biasing modes - digital control via a TTL interface and analog control via a biasing circuit. This two-stage amplifier is available as a chip measuring 2.87 x 1.37 x 0.1 mm and is ideal for X-band applications.
