1.8 Volts Low Noise Amplifier For 1575 Mhz Gps Applications Using The Sige:c Bfp740f Tranistor

• 1575.42 MHz GPs Overview • BFP740F in TSFP-4 package is evaluated for a GPs LNA application. Note TSFP-4 package is only 1.4 x 1.2 x 0.55 mm high. Design Goals: Gain = 20 dB min, Noise Figure = 0.8 dB max, Input / Output Return Loss 10 dB or better, current < 10 mA from a 1.8 Volt power supply • Printed Circuit Board used is Infineon Part Number 740F-080404 Rev A. Standard FR4 material is used in a three-layer PCB. Please refer to cross-sectional diagram below. • Low-cost, standard "0402" case-size SMT passive components are used throughout. Please refer to schematic and Bill Of Material. The LNA is unconditionally stable from 5 MHz to 8 GHz. • Total PCB area used for the single LNA stage is 40 mm². Total Parts count, including the BFP740F Transistor is 11.
