Title: Wanted: Large quantity of 70MHz transceiver
Post by sharnyo on Dec 3rd, 2007 at 5:37am
Hi,

My organization is looking to procure large quantity of 70 MHz transceivers with 5W for C-band (used).

Please email me your quotation.

Thanks.

Do you mean BUC ?   What is your location?

A 70 MHz transceiver normally comprises an up-converter to get from the 50 - 90 MHz band to a 40 MHz wide section of the 6 GHz transmit band.    You then add, for example, a 5 watt C band high power amplifier (C band in and C band out).

On the receive side there is a down-converter that may be tuned to a 40 MHz wide segment of the 4 GHz band.  Note that you need an LNA, not an LNB.  This downconverter brings out a block of frequencies 50 - 90 MHz to go to the modem receive input.

A 70 MHz modem transmits and receives in the range 50 - 90 MHz.

If you already have a large number of 70 MHz modems you need transceivers to make use of them.  If you have no modems then I would recommend, for least cost, L band modems plus LNB and BUC.

Best regards, Eric.

We are looking for a complete set of 70 Mhz transceiver not BUC.

The transceiver consists of the parts that is mentioned by Eric. It includes LNA.
