MKUPA23CM-50WB

MKU PA 23CM-50W B, Leistungsverstärker

1240 … 1300 MHz • 50 W
Linearer Hochleistungsverstärker für das Amateurfunkband 23 cm


Große Leistung, hoher Wirkungsgrad und beste Linearität erreicht unser Leistungsverstärker für das 23 cm Amateurfunkband. Die eingesetzten LDMOS-Transistor mit einer Versorgungsspannung von nur +28 V eingesetzt erlauben einen Betrieb ohne Hochspannungstrafos, Vorheizen und lästiges Nachstimmen. Der Verstärker lässt sich durch seine kompakten Maße nahe der Antenne montieren um Leistungsverluste durch zu lange Koaxialkabel zu vermeiden.

Kompakte Bauform (80x60x20)
Hohe Leistung bezogen auf die Baugröße 
Geringes Gewicht

The compact power amplifier for the 23 cm band combines small size and light weight with high power and efficiency thanks to LDMOS technology. Thus mounting close to the antenna is eased and plenty of applications become possible. E.g. analog and digital transmissions using COFDM-Systems with QPSK, QAM modulation and DAB, DVB.
  • LD-MOSFET technology
  • Good linearity
  • High efficiency
  • Reverse polarity protection
  • Monitor output for forward power detection (DC voltage)
  • Digital broadcast systems (DAB, DVB)
  • COFDM systems using modulation types QAM, QPSK
  • Analog transmission systems
Please notice the following:
  • Further information about dimensioning of heat sinks is available on our FAQ site.
  • Attention: The recommended fans need a supply voltage of 24 ... 28 V DC.
  • The technical specifications refer to room temperature.
Our power amplifiers of the MKU-series are exclusively intended for amateur radio applications and will only be sold to radio amateurs with a licence.
