1. A transmitter for wireless communication, comprising:
- a wideband tunable modulator, wherein the wideband tunable modulator includes an amplifier, and wherein a bandwidth of the amplifier is compensated for by using an inductive peaking technique;
a number of power amplifiers, wherein a particular power amplifier is associated with a particular frequency range; and
a wideband power amplifier (PA) driver configured to;
receive an output signal from the wideband tunable modulator;
amplify the output signal; and
send the amplified output signal to at least one of the power amplifiers.

11. A method for generating a transmitter output for wireless communication, comprising:
-
receiving a baseband signal; modulating the baseband signal onto an RF carrier, wherein the RF carrier has a frequency that ranges from 300 MHz to 3.6 GHz, wherein modulating the baseband signal is performed by an on-chip tunable modulator, wherein the on-chip tunable modulator includes an amplifier, and wherein a bandwidth of the amplifier is compensated for by using an inductive peaking technique; pre-amplifying the modulated signal using a single on-chip amplifier driver regardless of the RF carrier frequency; and sending the pre-amplified modulated signal to a power amplifier selected from a group of power amplifiers based on the RF carrier frequency. - View Dependent Claims (12, 13, 14, 15, 16, 17)
