MC13142中文资料摩托罗拉数据手册PDF规格书

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 Intermediate Frequency amplifier (IFamp) and a dc control section. The wide mixer IF bandwidth allows this part also to be used as an up converter and exciter amplifier.
