The AD8354 is a broadband, fixed-gain, linear amplifier that The noise figure is 4.2 dB at 900 MHz. The reverse isolation operates at frequencies from 1 MHz up to 2.7 GHz. It is (S12) is −33 dB at 900 MHz. intended for use in a wide variety of wireless devices, including cellular, broadband, CATV, and LMDS/MMDS applications. The AD8354 can also operate with a 5 V power supply; in which case, no external inductor is required. Under these By taking advantage of ADI’s high performance, complementary Si conditions, the AD8354 delivers 4.88 dBm with 20 dB of gain bipolar process, these gain blocks provide excellent stability at 900 MHz. The dc supply current is 26 mA. At 900 MHz, the over process, temperature, and power supply. This amplifier is OIP3 is greater than 19 dBm; at 2.7 GHz, the OIP3 is 15 dBm. single-ended and internally matched to 50 Ω with a return loss The noise figure is 4.4 dB at 900 MHz. The reverse isolation of greater than 10 dB over the ful operating frequency range. (S12) is −33 dB. The AD8354 provides linear output power of nearly 4.3 dBm The AD8354 is fabricated on ADI’s proprietary, high performance, with 20 dB of gain at 900 MHz when biased at 3 V and an 25 GHz, Si complementary, bipolar IC process. The AD8354 is external RF choke is connected between the power supply and available in a chip scale package that uses an exposed paddle for the output pin. The dc supply current is 24 mA. At 900 MHz, excellent thermal impedance and low impedance electrical the output third-order intercept (OIP3) is greater than 18 dBm; connection to ground. It operates over a −40°C to +85°C at 2.7 GHz, the OIP3 is 14 dBm. temperature range, and an evaluation board is also available.
