The R&S® FK855C1 is a member of the R&S® Series 2000 HF transceiver family. It matches the R&S® XK2500 transceiver to rod, whip and broadband antennas.
It can handle power up to 400 W CW and PEP at a 100% duty cycle. The input power is adapted automatically by the R&S® Series2000 transceiver. The R&S® FK855C1 operates in the frequency range 1.5 MHz to 30 MHz, where it performs an antenna impedance transformation into 50 Ω in both the receive and transmit modes. Additionally, it provides preselection in the receive mode.
DesignThe rugged design of the R&S® FK855C1 allows it to be operated continuously 24 hours a day.
BITEThe ATU is included in the continuous monitoring of the entire system so that deviations from the normal operating status are displayed on the control unit.
EMC and overvoltage protectionAll circuit boards are equipped with EMC filters. For protection against overvoltage as produced by lightning strokes to the antenna, the R&S® FK855C1 output is provided with lightning protection.
