It features high gain, low operating Good Noise Figure current, good noise figure with good input and output return loss. Power consumption can be further reduced ROHS compliant by reducing the quiescent bias current using two external Halogen free bias resistors. The device can be easily matched at different Advanced enhancement-mode PHEMT Technology frequencies to obtain optimal linearity performance at those frequencies. QFN 3X3 16-Lead standard package Lead-free MSL1 MGA-31816 is especially ideal for 50 W wireless infrastruc- ture application operating from 1.5 GHz to 4 GHz frequency Specifications range applications. With the high linearity, excellent gain flatness and low noise figure the MGA-31816 may be At 1900 MHz, V = 5 V, I = 60 mA (typ) 25 C dd dd utilized as a driver amplifier in the transmit chain and as a OIP3 = 40.2 dBm second stage LNA in the receiver chain. Noise Figure = 1.56 dB This device uses Avago Technologies proprietary 0.25 mm Gain = 19.4 dB GaAs Enhancement mode PHEMT process. P1dB = 20.7 dBm Pin connections and Package Marking Note: 1. The MGA-31816 has a superior LFOM of 15.8 dB. Linearity Figure of Merit (LFOM) is essentially OIP3 divided by DC bias power. 31816 Attention: Observe precautions for YYWW handling electrostatic sensitive devices.
