Digital Step Attenuators support 5G frequency demands
pSemi Corporation, a Murata company focused on semiconductor integration, announces the expansion of its digital step attenuator (DSA) portfolio with two new high-performance DSAs, PE43610 and PE43614. Featuring industry-leading attenuation accuracy, the PE43610 and PE43614 DSAs support the entire 9 kHz–13 GHz and 9 kHz–45 GHz frequency ranges, respectively. Ideal for 5G test-and-measurement applications, these DSAs exemplify pSemi’s […]
RF switches, Part 2: Analog and MEMS switches
Part 1 of this FAQ looked at the venerable electromechanical RF switch – still widely used in some applications, where it is the only viable option—and the use of PIN diodes as RF switches. This part looks at analog and MEMS-based switches. Q: What is an analog switch? A: It’s conceptually straightforward: in basic form, […]
RF switches, Part 1: Mechanical and PIN-diode switches
There’s a ubiquitous and increasing need to switch RF signals ranging into the tens of GHz; four basic switch technologies – electromechanical, PIN diode, analog, and MEMS – are available, each with different features and capabilities. The need to switch RF signals has been a necessary design function since the earliest days of “wireless.” This […]
