Product Description

Stanford Microdevices’ SCA-16 is a high performance Gallium

Arsenide Hetrojunction Bipolar Transistor MMIC Amplifier.

A Darlington configuration is utilized for broadband

performance up to 3 GHz. The heterojunction increases

breakdown voltage and minimizes leakage current between

junctions. Cancellation of emitter junction non-linearities

results in higher suppression of intermodulation products.

Typical IP3 at 50mA is +28dBm.

These unconditionally stable amplifiers provides 15dB of gain

and +14.5dBm of 1dB compressed power and requires only

a single positive voltage supply. Only 2 DC-blocking capaci-

tors, a bias resistor and an optional inductor are needed for

operation.

This MMIC is an ideal choice for wireless applications such

as cellular, PCS, CDPD, wireless data and SONET.
