RF Measuring Receiver
January 2002
The LT
5504 is an 800MHz to 2700MHz monolithic inte-
grated measuring receiver, capable of detecting a wide
dynamic range RF signal from –75dBm to +5dBm. The
logarithm of the RF signal is precisely converted into a
linear DC voltage. The LT5504 consists of RF/IF limiters,
an LO buffer amplifier, a limiting mixer, a 3rd-order
450MHz integrated low pass filter, RF/IF detectors and an
output interface. The ultrawide dynamic range is achieved
by simultaneously measuring the RF signal and a down-
converted IF signal obtained using the on-chip mixer and
an external local oscillator. The RF- and IF-detected sig-
nals are summed to generate an accurate linear DC voltage
proportional to the input RF voltage (or power) in dB. The
output is buffered with a low output impedance driver.
