Transverters – “Take’s Us Somewhere Else” 50 MHZ and Above
2304 MHz • 3456 MHz • 5706 MHz • 10368 MHz • And Higher? • We have allocations PAST 250 GHZ Do You Want TO Try ->
A Transverter is a RF device that consists of an Upconverter and a Downconverter in one unit. • Transverters are used in conjunction with transceivers to change the range of frequencies over which the “Transceiver” can operate. What Is A Transverter?
Transverters are most commonly used to convert radio transceivers designed for use on HF to operate on higher frequency (VHF) bands. • I.E 10 meters to 6 Meters / 2 Meters / 1.25 Meters. • Transverters are most commonly used to convert radio transceivers designed for use on the VHF 144 MHZ band (2 meters) to operate on even higher frequency bands (Microwave). • I.E. 2 Meters to 1296 / 2304 / 3456 / 5760 / 10.368 • A transceiver - HF or 144 MHZ - used in this fashion is referred to as an “IF” radio. • Indicating that it connects into the “IF” the Intermediate Frequency in the chain of the transceiver’s stages. Transverters Play Well With Others!
To use amateur frequencies above 1.3 GHZ “As a General Statement” there really is no “Off The Shelf” equipment - the little there is available is quite expensive – and a transverter can be used to get you to higher frequencies. • Instead of building a 2304 Mhz (2.4 GHZ) radio from the ground up that will have limited features - an off the shelf radio packed with features such as (all modes, high RX gain, large tuning range, and most cases small in size). • We can have success by using an off the shelf radio as an intermediate frequency to drive a transverter. Why Do We USe a Transverter?
A transverter just an extra stage with another with a mixer and oscillator. • AS An Example: • The transmit output of the 2m radio is passed through an attenuator to limit the signal - low enough - to be mixed with the LO “local oscillator” of the transverter. • (144Mhz + 1152Mhz = 1296Mhz) The transverter “ADDS” the required 1152 mhz in the mix. • This “Mix” is passed through a band pass filter to produce the final output frequency (1296Mhz). • The signal is amplified and then sent out the antenna port. How IT Works?144 mhz to 1.2 ghz“TRANSMIT SIDE”
On receive the same happens again. • The incoming RF signal is amplified and then mixed with the transverter LO (local oscillator) to produce 144Mhz for the radios input. How IT Works?1.2 ghz to 144 mhz“receive SIDE”

Whatever mode you input to the transverter – that same mode will come out. • Transverter does not need a mode change. • 144 MHZ FM IN –> 1296 MHZ FM OUT. What goes in Comes out.
Transverter “design principles” are the SAME for all frequencies. • Higher frequencies have one common issue “Frequency Stability”! • Tighter design and setup is required the higher you go in frequency. • Temperature Control is CRITICAL! • Frequency stability with 10MHz an external reference i.e. GPS is required. • YES – It can get complicated! The Numbers Are The same!.
