Introduction

The SKY13290 - 313LF is a high power, pHEMT Single Pole Double Throw (SPDT) switch. The switch is designed for use in systems operating from 20 MHz to 2.5 GHz for which low loss, high isolation, low control voltage, and ultra - miniature package size are required. The device is controlled with positive, negative, or a combination of both voltages. The RF signal paths within the device are fully bilateral. The SKY13290 - 313LF is manufactured in a compact, low - cost 2 x 3 mm, 6 - pin Quad Flat No - Lead (QFN) package. The SKY13290 - 313LF is controlled using two voltage inputs, V1 and V2 (pins 6 and 4, respectively). Depending on the voltage level applied to these pins, the common RF port (J1) is connected to one of two RF ports (J2 or J3) using a low insertion loss path, while the path between J1 and the other RF port is in its isolation state. When the control voltages are toggled, the states between J1 and J2, as well as J1 and J3, are also toggled.

Features

• Broadband frequency range: 20 MHz to 2.5 GHz
• Very low insertion loss, 0.4 dB typical @ 0.9 GHz
• High isolation: 26 dB typical @ 0.9 GHz
• High input power compression: 0.1 dB @ > +40 dBm
• Low current consumption: <100 μA @ 3 V
• Ultra - miniature, QFN (6 - pin, 2 x 3 mm) package (MSL1, 260 °C per JEDEC J - STD - 020)

Applications

Transmit/receive switching for telematic systems at elevated power levels
