MKU PA 133 HY2
Linear Power Amplifier for the 23 cm Band
1260 ... 1300 MHz • 30 W
This series of power amplifiers for the 23 cm band uses LD MOSFET Modules. Due to their linearity and thermal stability the amplifiers are excellent for all analog and digital modes in amateur radio. Typical examples are SSB, CW, ATV and DATV (digital amateur radio television).
