LTC5535
APPLICATIO S I FOR ATIO
Applications
The LTC5535 can be used as a self-standing signal strength
measuring receiver for a wide range of input signals from
–32dBm to 10dBm for frequencies from 600MHz to 7GHz.
The LTC5535 offers increased baseband bandwidth com-
pared to other Schottky diode detectors. Table 1 shows
that the baseband (demodulation) bandwidth is typically
12MHz at an RF input signal level of –10dBm. The baseband
bandwidth is largely independent of the RF input signal
frequency over the range of 600MHz to 7GHz.

The LTC5535 can be used as a demodulator for AM and
ASK modulated signals. Depending on specific application
needs, the RSSI output can be split between two branches,
providing AC-coupled data (or audio) output and a
DC-coupled RSSI output for signal strength measure-
ments and AGC.
