Circuit for switching a mobile radio transmitter between two modulation operation modes |
| 摘要 |
In the position for EDGE modulation, the changeover switch (S1) connects an input of the battery voltage modulator (16) to an output of the amplitude comparator (12) In the GMSK position, the signal (R1) for the variable gain amplifier (14) setting is applied directly to the input of the battery voltage modulator.
