Evaluation Kit for the CMX992

EV9920B

Product Data
EV9910B and EV9920B User Manual (rev6)

Features:

  • Allows Full Evaluation of the CMX992
  • Operational (Evaluation) Frequency Range:
    100MHz to 1GHz
  • 450 to 470 MHz Default Operation
  • On-board
    • CMX992 IC
    • LNA
    • I/Q or IF Output
    • Selectabe IF Filters
    • Test Access
  • PC Control Interface Available

Applications:

  • For the Evaluation, Demonstration and Design-In of the CMX992 Quadrature/Low IF Receiver IC

Supply Requirement:

  • 7.2V (typ) power supply

The EV9920B allows the evaluation of the CMX992 Quadrature/Low IF Receiver.

** The CMX992 includes only the receiver and IF LO sections of the CMX991 and is ideal for applications that do not require the CMX991 transmitter, for example when a linearised transmitter is required, in which case the CMX998 Cartesian loop transmitter IC could be used for Tx and the CMX992 for Rx.**

Access is provided to all CMX992 RF, baseband and control signals by either connector 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 and the overall evaluation frequency range of this Evaluation Kit is for RF frequencies between 100MHz and 1GHz, with default operation over 450 to 470 MHz. In the form of a populated PCB, this flexible Evaluation Kit enables users to configure and evaluate the CMX992 devices for various applications and frequency bands.

The on-board CMX992 IC is controlled via its C-BUS serial interface.
The PE0003 Interface Card is available separately to support PC-based control of the EV9920B.
The PE0003 uses ES9910xx.exe PC software, part of the ES9910xx.zip file, which is available via the download hyperlink in the Support Package area below.

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.
