TRANSVERTER SYSTEMS

LT SERIES 50MHz - 2304MHz.

The addition of an SSB Electronic transverter to your HF or VHF radio will yield a system of un-matched performance that will outperform any multi-mode radio manufactured today. Our transverter systems are the choice of EME, weak signal, contest, and OSCAR operators world-wide.

VHF / UHF Transverters -- General Specifications

VHF & UHF models utilize: Low noise GaAsFET high dynamic range preamplifers, three pole post preamp filters, High Level +17 dBM Schottky Double Balanced Mixers (DBM's) on receive yielding input 3rd order intercept points of +7dBM and output 3rd order IP's of up to +27dBm. Depending upon model, either a high level or low level DBM is used on transmit. All receive mixers are terminated with diplexers. 28MHz.-IF operation is featured and separate IF In/Out BNC connectors are provided. All IF and RF switching relays are built in. RF IN/OUT is common to one N-connector, however: RF IN/OUT can be separated if desired for EME dual feed line operation or to eliminate the input relay on a high power linear amplifier. All transverter are housed in an attractive cabinet and include: dual local oscillator strings for IF QSY or 435MHz operation (LT70S) plus a built in power meter. Drive requirements are: 1.0mW - 500mW via a back panel adjustable attenuator. 13.8VDC operation @ 3.5A

SHF Transverters 903MHz. - 2304.0MHz. -- General Specifications

Our SHF series of transverters now include two new transverters for 1296MHz, 2304MHz, 1269MHz. and 2400.0MHz. The LT230S & the LT130S transverters utilize Schottky Double Balanced Mixers (DBM) for high dynamic range on both transmit and receive, a pHEMT front end + helical filters for ultra low noise figures and the ultimate in out of band rejection. A GaAsFET final amplifier stage is employed on the LT130S to achieve 10 watts output on 2304MHz. Front Panel controls include: Off/On, Manual PTT, Variable IF attenuators for both Tx and Rx plus a power output meter. 144MHz-IF operation is standard, and IF drive requirements are 100mW - 10W. These transverters our housed in an attractive cabinet and include: built in blowers, all RF & IF relays, 13.8VDC operation. Models are available for Phase IIID operation at 1269.0MHz and 2400MHz.

For 903Mhz. we offer the LT33S transverter. This transverter utilizes an active GaAsFET mixer on receive and bipolar mixers on transmit. 144MHz.-IF operation is featured and input IF TR switching is provided. IF drive requirements are 100mW - 10W. This transverter is housed in an attractive cabinet and features a built-in power meter, dual Local Oscillator strings for IF QSY, plus 13.8VDC operation.
