The AD8353 is a broadband, fixed-gain, linear amplifier that The noise figure is 5.3 dB at 900 MHz. The reverse isolation operates at frequencies from 1 MHz up to 2.7 GHz. It is (S12) is −36 dB at 900 MHz and −30 dB at 2.7 GHz. intended for use in a wide variety of wireless devices, including cellular, broadband, CATV, and LMDS/MMDS applications. The AD8353 can also operate with a 5 V power supply; in which case, no external inductor is required. Under these By taking advantage of Analog Devices, Inc., high performance, conditions, the AD8353 delivers 8 dBm with 20 dB of gain at complementary Si bipolar process, these gain blocks provide 900 MHz. The dc supply current is 42 mA. At 900 MHz, the excellent stability over process, temperature, and power supply. OIP3 is greater than 22 dBm and is 19 dBm at 2.7 GHz. The noise This amplifier is single-ended and internal y matched to 50 Ω figure is 5.6 dB at 900 MHz. The reverse isolation (S12) is −35 dB. with a return loss of greater than 10 dB over the ful operating frequency range. The AD8353 is fabricated on Analog Devices proprietary, high performance, 25 GHz, Si complementary, bipolar IC process. The AD8353 provides linear output power of 9 dBm with 20 dB The AD8353 is available in a chip scale package that uses an of gain at 900 MHz when biased at 3 V and an external RF exposed paddle for excel ent thermal impedance and low choke is connected between the power supply and the output impedance electrical connection to ground. It operates over a pin. The dc supply current is 42 mA. At 900 MHz, the output −40°C to +85°C temperature range, and an evaluation board is third-order intercept (OIP3) is greater than 23 dBm and is also available. 19 dBm at 2.7 GHz.
