LOW POWER DC – 1.8 GHz
LNA, MIXER and VCO
The MC13142 is intended to be used as a first amplifier, voltage controlled
oscillator and down converter for RF applications. It features wide band
operation, low noise, high gain and high linearity while maintaining low
current consumption. The circuit consists of a Low Noise Amplifier (LNA), a
Voltage Controlled Oscillator (VCO), a buffered oscillator output, a mixer, an
SEMICONDUCTOR
TECHNICAL DATA
Intermediate Frequency amplifier (IF ) and a dc control section. The wide
amp
mixer IF bandwidth allows this part also to be used as an up converter and
exciter amplifier.
