The resistors R1 and R2 are chosen to set the base of TR1 to around the mid point. The RF Line used by Motorola consists of measuring h FE at the data sheet conditions and color coding the device to predetermined hFE ranges within the normal hFE limits. If more than a maximum voltage rating is applied to a transistor, it can be permanently damaged. Los MRF455 / MRF453 / MRF460 tienen una mayor cifi-a de mérito que los tres dispositivos tratados antes. The value of R3 has been determined experimentally; it depends also on the Hfe of T2 so you may need to tune the value of R2. pdf), Text File (. in stock, matched pair, same specification as MRF454 but with advanced gain: hfe 48 to 155 (min to max) standard MRF454 is 40 to 150 (min to max) SRF3775 = high gain MRF455: Motorola : 9403 : in stock, same specification as MRF455 but with advanced gain: hfe 38 to 155 (min to max) standard MRF455 is 10 to 150 (min to max) SRL035.
