IQ Direct Conversion Modulator / Demodulator
The PV5870 is a direct conversion quadrature modulator / demodulator designed for communication systems
requiring excellent linearity with the lowest power consumption in the industry. The device is optimized for wideband applications with RF inputs ranging from 400 –3600MHz.
Benefits of the component include excellent amplitude and phase balance, low conversion loss with low noise
figure, very low DC offset, and low power dissipation. Intermodulation products IM2 and IM3 can be optimized
through adjustment. RF, LO and baseband interfaces are fully differential. The baseband outputs of the device can
interface directly to baseband amplifiers or low-pass filters.
The excellent linearity of the PV5870 direct conversion quadrature demodulator can improve receiver dynamic
range and significantly reduce bill of materials cost by eliminating the need for IF signal processing components.
Performance as a modulator is equally impressive. Excellent sideband suppression of >40dBc and carrier leakage of
<-40dBm are achievable without adjustment for 900MHz applications. The on-channel LO input has a broad
operating range from -6dBm to +6dBm. The modulator core operates from a 1.8V power supply while providing an
OIP3 of +21dBm and OIP2 of +60dBm along with a P1dB of +7.5dBm at 900MHz. The LO path uses a +3V power
supply that can be regulated as low as 2.85V.

Notes:
1. Logic “0” on HLC pin 4 can be used to increase input referred P1dB to +21dBm. This is normally considered a temporary
operating condition and will increase conversion loss. It can also be used to increase the frequency range to 4GHz.
