Stanford Microdevices’ SCA-15 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 +27dBm.

These unconditionally stable amplifiers provides up to 12dB

of gain and +13.5dBm of 1dB compressed power and

requires only a single positive voltage supply. Only 2 DC-

blocking capacitors, 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.
