SNA-176
DC-10 GHz, Cascadable
GaAs MMIC Amplifier
Product Description
Sirenza Microdevices SNA-176 is a GaAs monolithic
broadband amplifier (MMIC) housed in a low-cost surface
mountable stripline packageꢀ At 1950 MHz, this amplifier
provides 12dB of gain when biased at 50mAꢀ
External DC decoupling capacitors determine low frequency
responseꢀ The use of an external resistor allows for bias
flexibility and stabilityꢀ
Product Features
Cascadable 50 Ohm Gain Block
12dB Gain, +13dBm P1dB
1ꢀ5:1 Input and Output VSWR
Operates From Single Supply
Low Cost Stripline Mount Ceramic Package
Hermetically Sealed
These unconditionally stable amplifiers are designed for use
as general purpose 50 ohm gain blocksꢀ Also available in
chip form (SNA-100), its small size (0ꢀ33mm x 0ꢀ33mm)
and gold metallization makes it an ideal choice for use in
hybrid circuitsꢀ
