Typical Application

Description

The LT®5500 is a receiver front end IC designed for low voltage operation. The chip contains a low noise amplifier (LNA), a Mixer and an LO buffer. The IC is designed to operate over a power supply voltage range from 1.8V to 5.25V.

The LNA can be set to either high gain or low gain mode. At 2.5GHz, the high gain mode provides 13.5dB gain and a noise figure (NF) of 4dB. The LNA in low gain mode provides -14dB gain and an IIP3 of +8dBm at 2.5GHz.

The mixer has 5dB of conversion gain and an IIP3 of -2.5dBm at 2.5GHz, with -10dBm LO input power.
