The Benefits Of A Tunable RF Filter
 
By Kevin Harrison, NuWaves Engineering

Filters are a staple of RF designers everywhere, and especially in applications where the integrity of the signal cannot be compromised. When you’re only concerned about a single frequency, it’s relatively easy to add in a fixed-tuned filter. However, it becomes slightly more difficult when you need to cover multiple frequencies and can’t just utilize a roofing filter. To avoid having to use a bunch of individual filters, basically creating a complex switched filter bank module, a tunable filter may be the solution.

As more products use electronics and wireless, a bilogical antenna is the best first investment for internal RF testing.

Utilizing Modern Day MPMs For High-Power And High-Efficiency
White Paper | By Jose Gonzales, dB Control

The first MPM, developed in the early 1990s, used a solid state driver amplifier, based on MMICs or discrete RF power transistors, to drive a mini traveling-wave tube (mini-TWT), and combined these devices with a power supply and control circuits in a very compact enclosure.
