Application Note: Matching Differential Port Devices

Tue, 09 Mar 2010 14:05:00 GMT

Differential signaling is the primary choice for a low power RF interconnection because it provides superior immunity to noise by offering twice the signal swing for a given supply voltage. The out of phase property of a balanced pair has several other benefits: it rejects any common mode interference signal, cancels the even order distortions such IM2, and reduces Electromagnetic Interference (EMI), EMI emission, and susceptibility. However, this presents a challenge for RF designers to integrate differential devices together since the widely used S-parameter matching technique cannot simply be applied. This article depicts a simple generic technique to match differential impedance devices and gives some matching circuit examples.

Application Note: Impedance Matching Techniques For Mixers And Detectors

Fri, 05 Mar 2010 19:37:00 GMT

The use of tables for designing impedance matching filters for real loads is well known. Simple complex loads can often be matched by this technique by incorporating the imaginary portion of the load into the first filter element. This technique is rarely useful for matching diodes because the equivalent circuit for the diode must include several real and imaginary elements. A methodical technique for matching such complex loads to a transmission line will be described. Previous references to similar procedures were empirical in nature. No tables are used, but it is necessary to know the admittance of the diode in the frequency band of interest.

White Paper: Understanding Star Switching: The Star Of The Switching Is Often Overlooked

Wed, 03 Mar 2010 16:41:00 GMT

Switching is probably the most overlooked and undervalued part of a test system design. Great attention is spent selecting the measurement and stimulus instruments. But more often than not, the signal switching solution does not complement the instruments. It doesn't matter how accurate the instruments are if the signals pass through a poor switch to get to them. Engineers are familiar with test instruments because they have used them during their school years and at work in the lab and on the bench testing products or debugging new designs. So it's easy for them to select instruments for an automated test system. On the other hand, the engineers probably did not use switching in day-to-day testing and only consider switching a minor component in an automated test system.
