Low-loss RF switches feature constant impedance technology
Integrated Device Technology has announced the expansion of its RF product portfolio with two switches that offer low loss and high isolation, with a new-to-the-industry constant impedance technology, called Kz. The F2914 and F2915 are 50Ω SP4T and SP5T RF switches that exhibit insertion loss of only 1.1dB with corresponding IIP2 of 124dBm and IIP3 of 61dBm at 4GHz.
The products utilise IDT's Kz design technology to maintain a near-constant impedance when switching between RF ports, improving hot switching reliability and system response time while protecting downstream components from transients. The switches are suitable for base stations (2G, 3G and 4G), repeaters, ATE, digital pre-distortion, and point-to-point, public safety and cable infrastructures.
“Low-loss, high-isolation multiport switches with high linearity are important components in many of our customers’ applications,” said Chris Stephens, General Manager, RF Division, IDT. “By offering RF switches with the Kz innovative design technology, we provide our customers with a way to reliably ‘hot switch’ components with minimum voltage and impedance excursions.”
The switches are packaged in an industry-standard NBG24 4mm2 24 pin QFN package, allowing customers to take advantage of the switches on existing as well as new designs. Samples are available now. The F2914 is priced at $1.56 and the F2915 at $1.82 for 10,000 units.
