High-Speed Relay-Controlled Antenna Tuner - Kenwood TS-890S In-Depth Manual

TRANSMISSION CIRCUIT 03
The "Transmit IMD Characteristics (14.2 MHz, 100 W output power)" and "Transmit Spurious Response (14.2 MHz, 100
W output power)" graphs show the IMD characteristics and harmonic spurious response. The graphs prove superb anti-
distortion characteristics and clean output power.

High-speed Relay-controlled Antenna Tuner

The TS-890S has a high-speed relay-controlled antenna tuner, which digitally controls in a combination of capacitors of
different capacitance through switching relays. The digital control achieves high-speed tuning.
