Product Description

SCA-7

Stanford Microdevices’ SCA-7 is a high performance Gallium

Arsenide Hetrojunction Bipolar Transistor MMIC Amplifier. A

Darlington configuration is utilized for broadband perfor-

mance up to 3 GHz. The heterojunction increases break-

down voltage and minimizes leakage current between

junctions. Cancellation of emitter junction non-linearities

results in higher suppression of intermodulation products.

Typical IP3 at 40mA is +24dBm.

DC-3 GHz, Cascadable

GaAs HBT MMIC Amplifier

These unconditionally stable amplifiers provides 21dB of gain

and +12dBm 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.

Product Features

This MMIC is an ideal choice for wireless applications such

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

•High Output IP3 : +24dBm
