Supply Requirement:

  • 7.2V (typ) power supply

The EV9910B allows the evaluation of the CMX991 Quadrature/Low IF Transceiver.

The CMX991 is an RF Transceiver IC providing I/Q modulator and up-conversion, superheterodyne receiver and IF local oscillator.

Access is provided to all CMX991 RF, baseband and control signals by either connectors or test points.

Test access points are available to accept common test equipments, such as RF and baseband signal generators and spectrum analysers. All signal paths are matched by suitable components.

The EV9910B provides an optional lumped bandpass filter plus buffer amplifier at 460MHz (default) to aid evaluation. The overall evaluation frequency range of this Evaluation Kit is for RF frequencies between 100MHz and 1GHz, with default operation over 450MHz to 470MHz.

In the form of a populated PCB, this flexible Evaluation Kit enables users to configure and evaluate the CMX991 device for various applications and frequency bands.
The on-board CMX991 is controlled via its C-BUS serial interface. The PE0003 Interface Card is available separately to support PC-based control of the EV9910B.

Both EV9910B and EV9920B Evaluation Kits are similar, use the same printed circuit board, with different components fitted. The User Manual is also common to both kits.

EV9910B/9920B FAQ

Q. What spurious response rejection can I expect from the EV9910B/EV9920B receiver?

A. The EV9910B/EV9920B has been tested for receiver spurious responses to EN300-113 with a 9600 baud GMSK modem.
The performance was limited only by the image rejection (approximately 30dB), other rejections being greater than the required 70dB.
The user may provide additional image filtering between the LNA and mixer input; this is detailed in the user manual.
