1.1 Brief Description
The EV0171 Evaluation Kit comprises a single board containing the CMX017 UHF FM/FSK transmitter,
frequency and gain potentiometers, VCO tank circuitry and miniature control switches.
A multi-turn potentiometer allows the user to select an RF operating frequency between 860 - 935 MHz. The
operating bandwidth and centre frequency can be optimised by modifying the VCO tank components.
The board is powered from a single 6 - 12 V dc power supply. Regulation circuitry sets the analog (AVDD)
supply for 3V operation. CMX017 supply currents may be measured by removing appropriate jumpers.
A low profile 2-way DIL switch controls the device enable lines, to obtain CMX017 powersave and zero-power
modes.
Links, test points and an SMA connector provide access to various points in the circuit.
