The AD8354 is a broadband, fixed-gain, linear amplifier that
operates at frequencies from 1 MHz up to 2.7 GHz. It is
intended for use in a wide variety of wireless devices, including
cellular, broadband, CATV, and LMDS/MMDS applications. The noise figure is 4.2 dB at 900 MHz. The reverse isolation
(S12) is −33 dB at 900 MHz. By taking advantage of ADI’s high performance, complementary Si
bipolar process, these gain blocks provide excellent stability
over process, temperature, and power supply. This amplifier is
single-ended and internally matched to 50 Ω with a return loss
of greater than 10 dB over the full operating frequency range. The AD8354 can also operate with a 5 V power supply; in
which case, no external inductor is required. Under these
conditions, the AD8354 delivers 4.88 dBm with 20 dB of gain …
