MC13142

Order this document By MC13142/D Advance Information 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 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. Wide RF Bandwidth: DC–1.8 GHz Wide LO Bandwidth: DC–1.8 GHz Wide IF Bandwidth: DC–1.8 GHz Low Power: 13 mA @ VCC = 2.7 – 6.5 V High Mixer Linearity: Pi1.0 dB = 3.0 dBm Linearity Adjustment Increases IP3in Up to 20 dBm Single–Ended 50 Ω Mixer Input Double Balanced Mixer Operation Open Collector Mixer Output ...
