Minhe TR-SDR Switch for FT-818 IC-7100 IC-7300 K3 100W DC-160MHz with MX-S3, Radio Frequency Spectrum Add-On, Metal Enclosure, 12V Operation

Features:* Allows the and for TRX to use the same antenna simultaneously. In receive mode, the is connected to the antenna; in transmit mode, it is disconnected and grounded. The for TRX is permanently connected to the antenna.* If a separate receive antenna is used, the is fully protected during transmission.* The MX-S3 consists of two independent : an audio switch that switches the audio path and controls the antenna switch. An RF-shielded antenna switch that contains the antenna relay and receive input limiter.* High-quality connectors are used. The for TRX's PTT signal is used as a control signal. In transmit mode, the SDR's audio signal is muted and the for TRX's audio signal is .* Dual input fault for protection prevents antenna relay failure. A high-power input RF limiter suppresses high current, keeping the SDR's input voltage at a safe level. This for protection withstands the full power of the for TRX.* Provides for TRX PTT cable disconnect for protection, power failure for protection, and overcurrent for protection with a resettable fuse. It is recommended to power the transceiver from the same 12 V power supply (common ground required).* Additional external relays synchronized by the for TRX PTT signal can be controlled (current draws up to 200 mA), for example, for PA control, TX antenna detuning, receive antenna switching, base station automation, etc. This approach avoids RF ground loops when using multiple devices.Specifications:Part Name: TR-SDR SwitchMaterial: MetalColor: BlackFrequency: DC-60MHzMaximum Power: 100WInsertion Loss: 0.3dBOperating Voltage: 12V (10V-15V)Operating Current: <100mASWR: ≤ 1.5Connector: SL16Weight: Approx. 700g/1.5 lbsSize: 15 x 13 x 5cmPackage Contents:1 x MX-S3 Switch1 x Cable with for SMA Connector1 x Radio PTT Signal Interface Kit (Includes 3.5mm Adapter Cable, 1 x for RCA , 1 x for Yaesu 8-pin , 1 x for ICOM 13-pin )
