Dear Experts...

Anyone familiar with the term TRX Saturation ? the problem happens with the TRX running for a long time or running with high power.

we are finding this types of TRX's in our network and our contract with the vendor is already expired.Its ********....tey have already stopped their business in BD....

Anyone please give solution - what is the cause for TRX saturation?

Any solution to solve this prob i.e repair the faulty TRX?

If you have at least 2 trxs of the same model, try of remapping these 2 trxs, maybe this occurs for GSM on the trxs that are carrying BCCH - beacon, and always on full power ... usually bcch trx is with higher temperature than the other one carrying TCHs , ... please make that test and let us know.
Anyway how old are those trxs with overheating problem ?
These modules also have expiry date ... :)

Additionally :
The heat generated is maybe coming from some non-ideal aspects of the electronics components in TRX modules. Switching losses in transistors, on-resistance of the switching transistors, resistance in the inductor and capacitors, core losses in the inductor, contribute to final result - overheating of module components and cause even to module fail prematurely. Check all health of the modules ...

Let us know, think this could maybe resolve problem ...
Good luck, P:)
