SGA-4186
Product Description
DC-5000 MHz, Cascadable
SiGe HBT MMIC Amplifier
Sirenza Microdevices SGA-4186 is a high performance SiGe
HBT MMIC Amplifierꢀ A Darlington configuration featuring 1
micron emitters provides high FT and excellent thermal
perfomanceꢀ The heterojunction increases breakdown voltage
and minimizes leakage current between junctionsꢀ Cancellation
of emitter junction non-linearities results in higher suppression
of intermodulation productsꢀ At 850 Mhz and 45mA, the SGA-
4186 typically provides +28ꢀ3 dBm output IP3, 10 dB of gain,
and +14ꢀ6 dBm of 1dB compressed power using a single positive
voltage supplyꢀ Only 2 DC-blocking capacitors, a bias resistor
and an optional RF choke are required for operationꢀ
