RF switches feature constant impedance technology
IDT has announced two RF 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 innovative 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 suited for applications including: base stations (2G, 3G and 4G); repeaters; test and ATE equipment; digital pre-distortion; and point-to-point, public safety and cable infrastructures.
Chris Stephens, General Manager, RF division, IDT, commented: “Low-loss, high-isolation multiport switches with high linearity are important components in many of our customers’ applications. 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.”
Packaged in an industry-standard NBG24 4x4mm 24-pin QFN package, the F2914 is priced at $1.56 and the F2915 at $1.82 in 10,000 unit quantities. Samples are available now.
