DEMO-MGA-16X16B Datasheet, PDF (6/17 Pages) Broadcom Corporation. – Dual LNA for Balanced Application 450 – 1450 MHz

Typical 900 MHz RF Performance Plots
RF performance at T_A = 25° C, Vdd = 4.8 V, Idd = 60 mA. Measurements made on single-ended amplifier in LNA mode
tuned to 900 MHz, using Figure 5 demoboard and Figure 6 circuit. Signal = CW unless stated otherwise. IIP3 test condition:
FRF1-FRF2 = 1 MHz with input power of -20 dBm per tone.
