25GHz Transceiver from a Microwave Radio 131-142264-0119 TX 25550-26475mhz RX 24525-25450mhz SMA and SMB connections Size 6" x 3" x 3/4" The XCVR module consists of two functional circuitries: a TX circuitry and a RX circuitry It is in good shape. Comes with a 14 day warranty $6 shipping to the US., $17 to the rest of the world I will combine auction to lower shipping costs Interconnection Transceiver (15-pin Connector, Tyco P/N 1-292250-5) Pin # Signal A/D Name Range Function Notes 1 PA3 Gate Voltage A BX_VG3 0 to -2.5 VDC (Current = 10mA max) PA3 gate voltage 2 +5 VDC A XB_+5V +5.00 +/- 0.15 VDC +5.0V to BCC card Tie to Pin 2 of 21-pin Connector. 3 Mute/Unmute Signal D XB_Mute Mute: LOW, Unmute: HIGH LOW => 0 V, HIGH => +3.3 V Mute/Unmute Signal Line (from IFC, through XCVR to BCC) Tie to Pin 5 of 21-pin Connector. 4 -5.0 VDC A XB_-5V -5.00 +/- 0.15 VDC -5.0 V to BCC Tie to Pin 1 of 21-pin Connector. 5 -5.0 VDC Sequence A BX_-5V_Seq -5.00 +/- 0.15 VDC -5.0 V Return to IF Card Tie to Pin 21 of 21-pin Connector. This pin must NOT be tied to Pin 21 of 21-pin Connector. 6 Ground A GND 0 VDC Ground 7 PA3 Drain Voltage A BX_Vd3a 10.3 +/- 0.3 VDC (Current=1.2A max) PA3 Drain Voltage 8 PA3 Drain Voltage A BX_Vd3b 10.3 +/- 0.3 VDC (Current=1.2A max) PA3 Drain Voltage 9 PA2 Drain Voltage A XB_Vd2 7.25 +/- 0.23 VDC or 10.25 +/- 0.32 VDC PA2 Drain Voltage Read Back for Sequence Tie to Pin 14 of 21-pin Connector. 10 PA1 Drain Voltage A XB_Vd1 7.25 +/- 0.23 VDC or 10.25 +/- 0.32 VDC PA1 Drain Voltage Read Back for Sequence Tie to Pin 15 of 21-pin Connector. 11 Ground A GND 0 VDC Ground 12 PA3 Current Select A XB_Curr Sel 0 to 10.6 VDC Select PA3 Drain Current 13 PA Voltage Selection A XB_VPA_SEL Open or Ground PA Voltage Setting: "GND"=+10.25 VDC PA "OPEN"=+7.25 VDC PA HSTX only supports +10.25 VDC PA at this time. It is possible that HSTX can support +7.25 VDC PA in the future with mutual agreement between MTI and HSTX. 14 Spare N/C N/C N/C N/C 15 Spare N/C N/C N/C N/C Notes: a. PA3 is the last stage in TX chain. b. Vd2 is the drain voltage of the second from last stage. c. Vd1 is the drain voltage of the third from last stage.
