DESCRIPTION
Avago Technologies’ With high IP3 and low noise figure, the MGA-31689 may be utilized as a driver amplifier in the transmit chain and as second or third stage LNA in the receive chain. For optimum performance at lower frequency from 450 MHz to 1500 MHz, MGA-31589 is recommended. MGA-31689’s high gain and high linearity features are achieved through the use of Avago Technologies’ proprietary 0.25 Pm GaAs Enhancement-mode pHEMT process. Pin connections and Package Marking GND GND 16X FEATURES
x ROHS compliant x Halogen free x High linearity at low DC bias power [1] x High Gain x Low noise figure x High OIP3 x Advanced enhancement mode PHEMT Technology x Excellent uniformity in product specification x SOT-89 standard package Specifications At 1900 MHz, Vdd = 5 V, Idd = 168 mA (typical) at 25° C x OIP3 = 44.9 dBm x Noise Figure = 1.9 dB x Gain = 18.1 dB x P1dB = 27.6 dBm x IRL = 14.0 dB, ORL = 11.5 dB Note: 1. The MGA-31689 has a superior LFOM of 15.5. Linearity Figure of Merit (LFOM) is essentially OIP3 divided by DC bias power.
