It features high gain, low operating ROHS compliant current, low noise fi gure with good input and output return loss. Power consumption can be further reduced Good Noise Figure by reducing the quiescent bias current using two external Halogen free bias resistors. The device can be easily matched at diff erent Advanced enhancement-mode PHEMT Technology frequencies to obtain optimal linearity performance at those frequencies. QFN 3X3 16-Lead standard package Lead-free MSL1 MGA-31716 is especially ideal for 50 wireless infrastruc- ture application operating from DC to 2 GHz frequency Specifi cations range. With the high linearity, excellent gain fl atness and low noise fi gure the MGA-31716 may be utilized as a driver At 900 MHz, Vd = 5 V, Id = 68 mA (typ) 25 C amplifi er in the transmit chain and as a second stage LNA OI P3 = 39.5 dBm in the receiver chain. Noise Figure = 1.9 dB This device uses Avago Technologies proprietary 0.25 m Gain = 20.6 dB GaAs Enhancement mode PHEMT process. P1dB = 22.5 dBm Pin Connections and Package Marking IRL = 15.5 dB, ORL = 15.5 dB Note: 1. The MGA-31716 has a superior LFOM of 16.5 dB. Linearity-Figure-of- 31716 Merit (LFOM) is the ratio of OIP3 to total DC bias power. YYWW XXXX Attention: Observe precautions for handling electrostatic sensitive devices.
