Merits of a Balanced RF Amplifier
WanTcom specializes in designing RF Amps with unsurpassed low noise performance. The benefits of using a balanced amplifier to overcome bias and load variation issues that single ended amps experience are covered in this App Note. Read More>>

Introduction to Quad Hybrids
These devices provide a cost effective solution to splitting and recombining signals for push-pull and other phase sensitive RF applications.Read More>>

Ferrite Circulator IM Distortion Analysis
Renaissance Electronics takes you through the mathematical model analysis right through the hardware evaluation to prove the Intermodulation Distortion (IM) can be controls as long as you understand the effects of the magnetic fields during the design phase.      Read More>>

Designing Power Dividers
Power Dividers need accurate phase relationships to provide the lowest noise performance and flatest gain curve. The design must take these parameters into consideration so you can meet your system level performance budgets.  Read More>>

Introduction to Directional Couplers
Most directional couplers end up outside the box, so memory issues can be a concern, but not if you select the proper connectors to keep the IM as low as possible. This article covers the important design issues to optimize your design.  Read More>>

Fixed & Variable Attenuators
Attenuators come is a variety of configuration depending upon the circuit requirements, all introduce electro-magnetic coupling concerns, so calculate the important parameters prior to your final selection to get the right device for your critical circuit.  Read More>>
