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.
- Construction in milled aluminum and copper housing to ensure optimal heat transfer
- 50V LD MOSFET technology
- High linearity
- High efficiency (up to 45%)
- Detector output to monitor forward and reverse power (DC voltage)Switch on / off with DC voltage
- Over-temperature shutdown
