ZLPLL

Based on the Analog Devices ADF4351 PLL chip this self-contained board can be used as a local oscillator for VHF, UHF and Microwave projects.

Specifications:

31MHz to 4400MHz
Fractional-N synthesizer capable of 1KHz (or better) frequency resolution
2 x RF outputs +7dBm from 500MHz to 2GHz
4 software programmable output levels at 2dB increments
No Tuning required
Frequency selection to one of 16 preset values (optional)
RS232 interface for programing of frequency and power levels
Frequency offset for TX (optional)
Several reference frequency options:
- Internal OCXO or VCXO reference
- External Reference up to 100MHz
Automatically switch from internal to external frequency reference
CW Beacon firmware available

Having 2 high level outputs is useful for applications sharing the same LO module between 2 transverters, or driving separate RX and TX stages.
