CXG1017N

8 pin SSOP (Plastic)

E97756A79

GSM1800/1900 DPDT TX/RX Antenna Switch

Description

The CXG1017N is a high power DPDT switch
suitable for Digital Cellular applications. This device
is part of a growing family of MMIC Antenna switches
for digital cellular and cordless radios. It uses the
state-of-the-art Sony JFET process.

Features

• Positive voltage supply only

• Low insertion loss, typically 0.7dB at 33dBm input

level

• Stable Characteristics over wide temperature range

• Fast switching-100ns Typical

• Low current consumption, 400µA typical at 5.5V

• 8 pin SSOP package (3.0 × 6.4mm)

Applications

• GSM1800 handportable

• GSM1900 handportable

• DECT basestation/handportable diversity antenna

switching

• Other digital cellular and wireless local loop

applications

Typical Application

ESD

As with other GaAs semiconductors, ESD precautions

must be adhered to.

Control Voltage Selection, Vctl (H)

The choice of control voltage will determine the compression characteristic of the switch and the generation of
harmonics. The table above indicates the sensitivity of P0.1dB to control voltage, whilst the graphs below
indicate the sensitivity of harmonic levels:
