TSTM872-20 Datasheet | STMicroelectronics

DESCRIPTION The TSTM872-20 module is designed for high power, high efficiency, analog private mobile radio systems in the 806 - 870 MHz frequency range. A significant advantage of this module is its high RF power output performance and very low standby current. 1. RF Input 4. 12.5 Vdc VS3 2. 12.5 Vdc VS1 5.

Nor should the module be operated continuously at any of the specified maximum ratings. If the module is to be subjected to one or more of the maximum rating conditions, care must be taken to monitor other parameters which may be affected. DECOUPLING Failure to properly decouple any of the voltage supply pins will result in oscillations at certain operating frequencies. Therefore, it is remended that these pins be bypassed as indicated in the Module DC and Test Fixture Configuration drawing of this data sheet. MODULE MOUNTING To insure adequate...
