In this paper a new linear power control technique is presented to control the output power of cascode power amplifiers. Using this technique the output power of power amplifier can be controlled from the maximum output power to À 136 dBm, continuously. The characteristic of the output voltage versus control voltage is linear from À 15.9 to 18.6 dBm (a(More)
— In this paper, a new distributed active mixer is presented. The scheme is based on the conventional Gilbert-cell multiplier with complementary transconductance stage. By adding the preamplifier and non-uniform artificial transmission lines on the topology, the new distributed active mixer is obtained. Comparison of the new mixer with the topology in(More)
