A first pass success is always welcome. When the sucess is a high frequency device it is doubly so. The latest addition to the high frequency, silicon proven ASSP portfolio, is a high frequency, wideband amplifer fabricated in a 0.35um SiGe process.
It is fairly general purpose and can be used as gain block, an LNA etc. The basic features are as follows:
Features:
Usable frequency gain = 100 to > 2500 Mhz
19 dB typical ac gain at 900 Mhz, VCC = 2.7V
NFMIN = 1.2 dB at 900 Mhz
NFMIN = 1.5 dB at 2500 Mhz
1 dB compression point at 900 Mz = 2.9 dBm
1 dB compression point at 2500 Mz = 0.9 dBm
OIP3 at 1.5 Ghz = 15.0 dBm
OIP3 at 2.5 Ghz = 10.0 dBm
Power supply from 2.7 to 5.0 Volt
Power supply current typical = 4.7 mA
Reverse isolation s12 = -48.0 dB min.
The device was tested from -55 Degrees C to 125 Degrees C. An extended frequency test was also done at 5.0 Ghz. The gain dropped to 17 dB. Other parameters were also slightly affected.
