KIT 1,3 GHz 13G2B-28
Transverter
1296 ... 1298 MHz
The new transverter-kit for 23 cm represents the current status of amateur radio in the field of microwave technology. Revised by DB6NT, this transverter features excellent technical data and is suited for portable or stationary activities due to its small mechanical dimensions. By the use of additional power amplifiers this transverter module can be upgrated to a high performance transmit / receive system for 23 cm. All well-tried functions and features of the previous transverters are included.

- Transmit gain and receive gain separately adjustable
- Internal stabilized oscialltor with precision crystal heater (40° C)
- Control output for additional amplifier stages or a coaxial relay
- PTT can be switched by voltage on the IF connector or by connecting the PTT pin to ground
- Detector output (DC voltage) for monitoring the output power
- Small mechanical dimensions due to the use of state-of-the-art SMD parts
Important note
- To achieve a successful construction of this transverter the builder has to have experiences in the use and handling of SMD-parts. Further more experiences with smaller projects in microwave circuits arevaluable. The construction of this transverter KIT is NOT a beginners' project!
ESD sensitive devices (for example FETs) must be handled carefully. - The transverter KIT 1.3 GHz 13G2B-28 needs an additional external band pass filter for 1296 ... 1298 MHz, to achieve sufficient image rejection. Further information about supply and construction is included in these two files:
