The AD8354 is a broadband fixed-gain linear amplifier that operates at frequencies from 1MHz up to 2.7GHz. It is intended for use in a wide variety of wireless devices, includes cellular, broadband, CATV and LMDS/MMDS applications.
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 ohms with a return loss of greater than 10dB over the full operating frequency range.
The AD8354 provides linear output power of 4.3dBm with 20dB of gain at 900MHz when biased at 3V and an external RF choke is connected between the power supply and the output pin. The dc supply current is 24mA. At 900MHz, the output third-order intercept (OIP3) is greater than 18dBm at 2.7GHz, the OIP3 is 14dBm.
The noise figure is 4.2dB at 900MHz.
