Product no.: pmsdr_dwn_conv
It's a complete downconverter for the VHF-UHF bands, covering from about 90 Mhz up to 500 Mhz. The board can be added to the PMSDR as an option, extending the frequency range up to 500 Mhz. There are two preselection filters, for VHF and UHF bands, but it's also possible to exclude these filters in order to use external filters. A particular feature of this downconverter is the digitally tunable LO, from 10 up to 810 MHz; this allows use of a wide range of IF frequencies. Furthermore, the downconverter has also a build-in automatic T/R antenna switch, which permits use of a transceiver on the same antenna as the PMSDR (see Switchboard).
Furthermore, the downconverter has also a build-in automatic T/R antenna switch, which permits to use a transceiver on the same antenna with the PMSDR (see Switchboard).
Normally the antenna is connected to the PMSDR input. When the unit senses RF power on RTX, the antenna is connected to the RTX input. Three operating modes are available: passive, manual and automatic mode. When the PMSDR is not powered, the transceiver is connected to the antenna to avoid damage to the transceiver.
No external power required - low power cosumption design

Product no.: pmsdrswitchnachr
This is a small and compact optional automatic T/R switch plug-in board for the PMSDR. Normally the antenna is connected to the PMSDR input. When it senses RF power on RTX, the antenna is connected to RTX input. There are available three operating modes: passive, manual and automatic mode. When the PMSDR is not powered, the transceiver is connected to the antenna to avoid transceiver damage.
All SMT parts ready mounted.
The KIT contains a ready made backplane for existent PMSDR ( 3 BNC cuts)

Product no.: pmsdr_antiso
This is a broadband galvanic antenna isolator. A high quality transfomer permit the use from LW up to the UHF frequencies.
A ground loop in your receiver caused by antenna connection is very common if you have your computer connected to the same system. This type of ground loop problem can be solved by using suitable isolation between your receiver and the antenna cable.
The pcb accept also other transformers with different ratio follow packages (case style): SM22, KK81, W38, X65. There exist also the possibility to mount SMA, SMB or MMCX connectors.
In/out impedance : 50 Ohm (1:1 ratio)
Insertion loss: max. 1dB (2-50 MHz) / 3 dB(0,15-400MHz)
Maximum RF Power : 0,25W
The kit include:
