Figure 1. Mobile Phone Tx Power Control Application with a Capacitive Tap
Applications
The LTC5530 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 300MHz to 7GHz.
Operation at higher frequencies is achievable. Consult
factory for more information.
The LTC5530 can be used as a demodulator for AM and
ASK modulated signals with data rates up to 2MHz.
Depending on specific application needs, the RSSI output
can be split between two branches, providing AC-coupled
data (or audio) output and DC-coupled RSSI output for
signal strength measurements and AGC.
The LTC5530 can be used for RF power detection and
control. Figure 1 is an example of transmitter power
control, using the LTC5530 with a capacitive tap to the
power amplifier. A 0.5pF capacitor (C1) followed by a
200Ω resistor (R1) forms a coupling circuit with about
20dB loss at 900MHz referenced to the LTC5530 RF input
pin. In the actual product implementation, component
values for the capacitive tap may be different depending on
parts placement, PCB parasitics and parameters of the
antenna.
