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

• Single Transistor Oscillator with Collector, Base and Emitter Pinned Out

• Buffered Oscillator Output
