SGA-2263
Product Description
DC-5000 MHz, Cascadable
SiGe HBT MMIC Amplifier
Sirenza Microdevices SGA-2263 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 20mA, the SGA-
2263 typically provides +20ꢀ2 dBm output IP3, 14ꢀ7 dB of gain,
and +7ꢀ5 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
