1.8MHz-50MHz Antenna Sharing Device QSK TX/RX TR Switch 100W For SDR and Radio Generation IV
Features:
- Protective Circuit: It protects your device from being damaged when you forget to connect the radio T/R cable
- Wide Working Range: Its operating frequency extends to all short-wave bands, supporting all amateur radio bands of 1.8Mhz-50Mhz
- Improved Designed: A delay circuit is added to the fan, so when it stops transmission for 15 seconds, the fan will automatically stop working
- Special for SDR Device: It can make SDR and high-power short-wave transmitter share an antenna, ensuring that the SDR will not be burned while the short-wave transmitter transmits signals within 100W. At the same time, it ensures that the short-wave transmitter and SDR equipment are simultaneously applied to the same short-wave antenna to receive short wave signal.
- Fast Switching Speed: Adopted a subtle PIN short-wave RF dedicated switch, it is fast to switch T/RX. The switching time is less than 100μS in theory.
- Excellent Performance: The absolute output of the SDR end does not exceed -10dbm at 40m, the insertion loss is less than 0.3, the isolation is 55db, the standing wave is less than 1.4 (6m), and the other bands are less than 1.2.
- Ultra Quite Fan: for cooling high-power PIN ceramic diodes
- Built-in PTT IN and OUT interfaces to link short-wave transmitters to the power amplifier through the device
- Size: 150 x 105 x 55mm
- Power Supply: 13.8V
Package Included:
- 1 x Antenna Sharing Device QSK TX/RX Switch
