Using Single-ended S-matrices to Characterize Differential Components in Mobile Radio Design
In the past, individual RF or IF components tended to be based on differential topology. Widespread use is common within the wireless industry because this topology offers inherent noise immunity benefits. Although these balanced components provide good noise immunity, their structure gives RF designers headaches when characterizing and matching.
A method to accurately measure and characterize such circuits is desirable. The method described here provides a compact way to characterize the...
