LA1837 Overview
Key Features
- On-chip MPX VCO (no external components required)
- Adjacent channel interference rejection function (third and fifth order)
- Supports both the SD and the IF counting techniques
- The AM and FM SD sensitivities can be set independently
- The AM and FM output levels can be set independently
- Improved AM practical sensitivity and high-input distortion characteristics. Functions
- AM : RF amplifier, mixer, oscillator, IF amplifier, detector AGC, oscillator buffer, S-meter, narrowband SD, IF buffer
- FM-IF : IF amplifier, quadrature detector, S-meter, Scurve detector, IF buffer output
