LA8670M
No.4930-1/10
Overview
The LA8670M is a narrow band FM IF system for use in communication equipment. In addition to the functions
required for FM reception, the LA8670M provides a rich set of additional functions including noise detection and
field strength detection, and is thus optimal for cordless telephones.
Functions
First mixer, first local oscillator, first local oscillator buffer output, second mixer, second local oscillator
IF amplifier, limiter, quadrature detector
Signal meter
Noise detector, noise amplifier, noise wave detector, schmitt trigger
Features
Low voltage operation: VCC op=1.8 to 6V
Signal meter linear over a wide range (70dB typical)
High sensitivity, high intercept point
