MGA-31289

0.25W High Gain Driver Ampliﬁer

1500 - 3000 MHz

Data Sheet

Description

Features

Avago Technologies MGA-31289 is a 0.25W high gain

driver ampliﬁer MMIC with good gain ﬂatness, housed in

a standard SOT-89 plastic package. The device features

high linearity performance, excellent input and output

return loss, and low noise ﬁgure. The device can be easily

matched to obtain optimum power and linearity.

•ꢀ ROHS compliant

•ꢀ Halogen free

(1)

•ꢀ High linearity at low DC bias power

•ꢀ High Gain

•ꢀ Good gain ﬂatness

•ꢀ Low noise ﬁgure

MGA-31289 is externally tunable to operate within 1.5GHz

to 3GHz frequency range applications. With high IP3, low

noise ﬁgure and wideband operation, MGA-31289 may be

utilized as a driver ampliﬁer in the transmit chain and as a

second stage LNA in the receive chain.

•ꢀ Excellent uniformity in product speciﬁcation

•ꢀ SOT-89 standard package

Speciﬁcations

This device uses Avago Technologies proprietary 0.25um

GaAS Enhancement mode PHEMT process.

At 1.9GHz, Vd = 5V, Id = 124mA (typ) @ 25°C

•ꢀ OIP3 = 41.8dBm

Pin connections and Package Marking

•ꢀ Noise Figure = 2dB

•ꢀ Gain = 18.70dB; Gain Flatness (+/-50MHz) = 0.1dB

•ꢀ P1dB = 23.6dBm

12X

•ꢀ IRL = 16.2dB, ORL = 10.3dB

Note:

1. The MGA-31289 has a good LFOM of 14dB. Linearity Figure of Merit

(LFOM) is essentially OIP3 divided by DC bias power.
