Preliminary specification

High dynamic range dual LNA MMIC

CGY2105ATS

FEATURES

• Dual Low Noise Amplifier (LNA) Monolithic Microwave

Integrated Circuit (MMIC)

• Typical noise figure of 0.55 dB

• Typical gain of 16.3 dB at 1810 MHz

• Input IP3 of 13.5 dBm at 1810 MHz

• Low current of 58 mA at 2.5 V for each channel

• Low cost SSOP16 plastic package.

APPLICATIONS

• DCS1800

• PCS1900.

GENERAL DESCRIPTION

The CGY2105 is a dual Gallium Arsenide (GaAs) MMIC

amplifier designed for use in very low noise figure

applications, where high linearity is also required.

Excellent tracking between the two amplifiers is obtained.

Gain and noise figure variations with temperature are very

small.

The device is suitable for use in DCS1800 and PCS1900

base station applications.

It also provides high gain and very low noise performance

at frequencies between 1.0 and 2.5 GHz, as used in

Wireless Local Area Network (WLAN) applications.

A rematching of the application board might be necessary

for optimum performance.
