AD831 500MHz Bandwidth High Linearity Low Distortion Ac

The AD831 is a low distortion, wide dynamic

range, single chip mixer, suitable for HF and VHF Receiver RF-IF frequency,

second mixer in DMR base station, DC-baseband conversion, quadrature modulation

and demodulation, and ultrasound imaging, frequency shift detection and other

applications.

Feature:

The AD831 has provide +24 dBm

third-order intermodulation intercept point, realization of -10 dBm LO power,

without the need for a high power LO drive.

There is no corresponding shielding and

isolation problems, therefore, compared with the passive mixer to improve the

performance of the system, reduce the system cost.

The mixer is designed as a single power

supply, RF, IF and LO port with DC isolation capacitor, easy to use.

The operating frequency of the RF and LO

inputs can be as high as 500MHz.

IF output is single ended voltage output.

With 250 MHz output bandwidth.

A single resistor connected between pins

OUT and FB is used to set the gain.

The amplifier has low DC offset

characteristics, so it can be used in DC-baseband frequency conversion and

quadrature amplitude demodulation.

When the mixer's output amplifier and the

optimum source impedance, the SSB noise figure of the mixer is 10.3dB at 70MHz.

Different from the passive mixer, there is

no insertion loss, no need external duplex device, and no need passive

termination for AD831.
