Thank you very much. But very poor noise figure Single balanced active mixer BJT Single-ended input Differential LO Differential output QB provides gain for vin Q1 and Q2 steer the current back and forth at LO Gilbert Mixer Use a differential pair to achieve the transconductor implementation This is the. Bjt mixer design.
Bjt Mixer Design, In active region the BJT is modeled as. The RF signal at 4300 MHz is down converted into IF frequency of 200 MHz. Ideally to meet the low noise high linearity objectives of a mixer we need some circuit that implements a polarity-switching function in response to the LO input.
