MKU PA 23CM-1200W A, Power Amplifier
1280 ... 1300 MHz
1200 W
High power linear amplifier for the 23 cm amateur radio band
Our high-performance amplifier for the 23 cm amateur radio band achieves great performance, high efficiency and best linearity. In contrast to tube amplifiers, an LDMOS transistor with a supply voltage of only +50 V is used here. High-voltage transformers, preheating and annoying post-voices are a thing of the past! The amplifier can be mounted close to the antenna to avoid power losses due to long coaxial cables.
Included supply:
Cable lugs for the power supply
