What is GBPPR Zine: February 2011 Issue 82 about?
The document summarizes the construction of a narrowband 10.7 MHz intermediate frequency (IF) filter with approximately 30 kHz bandwidth for a 1 GHz radio frequency (RF) spectrum analyzer project. It uses four commercially available 10.7 MHz monolithic crystal filters purchased in matched pairs. The filters are connected in a circuit that transforms their 3,000 ohm impedance to the 50 ohm impedance of the spectrum analyzer using inductors and capacitors in an L-network configuration.
