SGA-4186

DC-5000 MHz, Cascadable

SiGe HBT MMIC Amplifier

Product Features

• High Gain : 9.2 dB at 1950 MHz

• Cascadable 50 Ohm

• Patented SiGe Technology

• Operates From Single Supply

• Low Thermal Resistance Package

Stanford Microdevices’ SGA-4186 is a high performance

SiGe Heterojunction Bipolar Transistor MMIC Amplifier. A

Darlington configuration featuring 1 micron emitters provides

high F

increases breakdown voltage and minimizes leakage current

between junctions. Cancellation of emitter junction non-

linearities results in higher suppression of intermodulation

products. At 850 Mhz and 45mA , the SGA-4186 typically

provides +28.3 dBm output IP3, 10 dB of gain, and +14.6

dBm of 1dB compressed power using a single positive

voltage supply. Only 2 DC-blocking capacitors, a bias

resistor and an optional RF choke are required for operation.
