The MC13143 is a high compression linear mixer with single–ended RF
input, differential IF output and differential LO inputs which consumes as
little as 1.8 mW. A new circuit topology is used to achieve a high third order
intermodulation intercept point, high linearity and high 1.0 dB output
compression point while maintaining a linear 50 Ω input impedance. It is
designed for Up or Down conversion anywhere from dc to 2.4 GHz.

Ultra Low Power: 1.0 mA @ VCC = 1.8 – 6.5 V

• Wide Input Bandwidth: DC–2.4 GHz

• Wide Output Bandwidth: DC–2.4 GHz

• Wide LO Bandwidth: DC–2.4 GHz

• High Mixer Linearity: P
