The usual players all showed up at this year’s Mobile World Congress in Barcelona with lots of improved devices, but no real game-changing breakthroughs... |
Active mixer differential to single-ended IF matching
While single-ended RF and LO input ports are becoming standard on high linearity active mixer ICs, integration of the IF output transformer is difficult and can be undesirable. A discrete balun approach delivers good performance over a relatively narrow IF bandwidth when compared to a transformer-based IF matching technique....
Microwave absorbers manage military electronics RF interference
The increased use of microwave electronics by today's military carries with it the increased potential for RF interference. Various types of microwave absorbing materials use either dielectric or magnetic loss to limit RF interference in military electronics equipment....
