Analog IQ Modulator / Demodulator Board
The Analog IQ Modulator / Demodulator board was designed for easy conversion of high bandwidth baseband signals (B = 100 MHz) to RF domain.
The main components of the Analog IQ - Board are one IQ-Modulator device (AD8349/Anlog Devices) and one IQ-Demodulator device (AD8347/Analog Device). Four low pass filters (baseband signal) and two voltage regulators are integrated on board too.
The IQ- modulator und -demodulator devices are supplied via separate local oscillator (LO) inputs. The LO frequency can be varied in the range from 0.8 to 2.7 GHz.
Many variable capacitors and resistors are used to allow easy tuning of IQ imbalance, carrier suppression, phase correction and amplification.
The board can be delivered with RF housing or as single PCB.
