AD831 500 MHz Bandwidth Low Distortion High Linearity Active RF Mixer Module

Description de AD831 500 MHz Bandwidth Low Distortion High Linearity Active RF Mixer Module

AD831 500 MHz Bandwidth Low Distortion High Linearity Active RF Mixer Module
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.
Features:
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.
