Communication receiver system having a voltage converter with an operating frequency below the receiver IF
First Claim
1. A communication receiver system for receiving coded signals and of the type having at least one predetermined intermediate frequency (IF) signal, comprising:
- decoder means for detecting and decoding received coded signals;
voltage converter means, connected to said decoder means, for generating a voltage greater than a supply voltage of said communication receiver system, and operating at a frequency below the frequency of the IF signal; and
frequency trim circuit means, connected to said voltage converter means, for controlling the operating frequency of said voltage converter means whereby interference with said IF signal is prevented.

Abstract
A communication receiver system for receiving coded signals and of the type having at least one predetermined intermediate frequency (IF) signal comprising a decoder for detecting and decoding the received coded signals and a DC/DC voltage converter circuit, connected to the decoder, for generating a voltage greater than the supply voltage of the communication receiver system at a frequency below the frequency of the IF signal. The system further comprises a frequency trim circuit, connected to the voltage converter circuit, for controlling the operating frequency of the DC/DC voltage converter circuit whereby interference with the IF signal is prevented.
