High Linearity Components Simplify Direct Conversion
Receiver Designs вЂ“ Design Note 418
Cheng-Wei Pei
Introduction
A direct conversion radio receiver takes a high frequency
input signal, often in the 800MHz to 3GHz frequency range,
and utilizes one mixer/demodulator stage to convert the
signal to baseband without going through an intermediate
frequency (IF) stage. The resulting low frequency (baseband) signal spectrum has useful information at frequencies from DC to typically a few tens of MHz. Designing
these receivers requires the use of very high performance
analog ICs. High performance direct conversion radio
receiver signal chains for applications such as cellular
infrastructure and RFID readers require high linearity,
low noise п¬Ѓgure (NF), and good matching between the
in-phase and quadrature (I and Q) channels.
The Right Components for the Job
Linear TechnologyвЂ™s LTВ® 5575 direct conversion demodulator has a combination of excellent linearity and noise
performance. The most important linearity speciп¬Ѓcation
for direct conversion mixers is the 2nd order intercept
point (IIP2) due to the 2nd order distortion product falling
within the baseband output spectrum, and the LT5575
boasts 54.1dBm at 900MHz (60dBm at 1900MHz). The LT5575 also has high 3rd order linearity and a low noise
п¬Ѓgure of 12.8dB. …
