Abstract:
A linear technology radio for use in satellite communication is provided. The linear technology radio includes: a pre-amplifier to amplify a Local Oscillator (LO) reference signal; an intermediate frequency (IF) amplifier to amplify an IF signal; a frequency multiplier to multiply the LO reference signal; and a mixer to mix the amplified LO reference signal and the amplified IF signal to generate a Radio Frequency (RF) signal, wherein a frequency band of the IF signal is fixed, a frequency band of the LO reference signal is variable, and a highest frequency of the LO reference signal frequency band is less than a lowest frequency of the IF signal frequency band.
