Removed from decommissioned Anritsu RF TX/RX test equipment - fully functioning prior to being "parted out"
Anritsu PDC Signalling Tester SPARE PART
Model: MD1623B
Module: RPP (Reverse RF Power Protection Control)
Anritsu ID numbers: RPP A402 342U921114 (PCB) A401 (RF detector)
SMA female input & output sockets
All wiring remains intact
Basic technical information:
The MD1623B both receives and transmits test signals in the 800Mhz & 1.8Ghz bands. This equipment was designed for use with the Japanese PDC cellphone system and dates from the late 1990's. The PDC system was finally turned off in Japan 2012. The RF output from the 1623B transmitter can be pushed to 50W and there is also the opportunity for mobiles under test to send RF into the wrong port. This would be not a good thing! If excessive RF found its way back to this equipment's receiver, extensive damage would result and this module forms part of this RPP system.
There are two main parts to this module, at one end is the RF detector and the other end has a very nice RF electromechanical relay.
If someone was looking at using the internal components, this RF relay is very interesting. Designed for use to around 2Ghz, it simply makes or breaks the continuity between the input and output SMA's. It looks to be a totally Anritsu product and is is very well designed and engineered. The RF relay "block" is removeable so it could be used standalone. Coil measures 800 Ohm centre-tapped.
There are no markings anywhere on the relay indicating a "type number"
I have attempted to show inside the RF relay housing, so the viewer can get an idea of the construction used.
I do NOT have any schematics or other Anritsu technical information - my comments are my own observations.
Dimensions: 170mm wide x 100mm deep x 30mm height (measurements include flanges and feedthroughs for signalling)
Weight: 350g
COSMETIC CONDITION:
Great condition, no damage to casing and all hardware is supplied
TESTING:
Removed from fully functional Anritsu 1623B equipment (I even had an old PDC mobile on hand!) I feel it is unlikely that the complete module will be of much interest as the equipment is very dated now (and PDC is not is use any longer) BUT that RF relay may be of particular interest.
