This device is intended for radio amateur shortwave transceiver 160 - 10 meter range.
It is based on the microprocessor STM32F100, the frequency synthesis chip SI5351.
All device status data is displayed on a 2.8 "color TFT display and all parameters and settings are stored in the non-volatile memory of the microprocessor.
This frequency synthesizer can be used for a transceiver or receiver with a multi-mode structure (CW / SSB / AM / FM), according to single, double and direct frequency conversion schemes. (The configuration for a particular device is configured in the service menu).
The synthesizer has an external UART RS232 port for managing the CAT protocol "Kenwood".

The supply voltage is 5-15V (Rated 12V)
The current consumption is 140mA with the backlight of the display and 100mA with the illumination off.
Logical levels on pins - Input / Output - TTL (0 - 3.3V)
Output RF voltage (SI5351) switchable - approximate values ​​of 190, 380, 550, 700 mV (Urms)
The output impedance (SI5351) is 50 ohms

To this device, you can connect an additional bandwidth filter module
