Title: Device and method for reinforcing acpr by gain modulation
Inventor: MOHINDRA RISHI
IPC: H04J13/00
Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To obtain a transmitter having a reinforced adjacent channel power ratio(ACPR) without depending on a high linear power amplifier by providing a transmission amplifier with a gain modulated by an envelope signal being proportional to a transmission signal. SOLUTION: A modulated RF signal s (t) is amplified by a power amplifier(PA) 175. The amplifier 175 outputs the amplified signal a1s (t). An envelope detector 177 receives the signal a1s (t) that is outputted from the PA 175 and subjected to RF amplification, detects and extracts an envelope signal e (t) from the received signal and offers the signal e (t) to the control port of the PA 175 directly. The signal e (t) modulates the gain of the PA 175 for linearization. In such a case, the signal e (t) is preferably matched with the square of the envelope change of the magnified RF signal a1s (t) and changes or modulates the gain of the PA 175.
