Vishay Intertechnology Inc. introduced a new series of radial-leaded, positive temperature coefficient (PTC) thermistors. Devices in the new TFPTL <http://www.vishay.com/doc?33027> series feature nickel thin film elements with positive temperature coefficients of + 4110 ppm/K, fast response time of < 2 s, and high stability over a wide temperature range from - 55 to + 150 °C.
Empower is pleased to be releasing the first models of its “Size Matters” high power PA product family. Packaged in a 5U, air cooled chassis and delivering over 1 kW of output power in the frequency ranges of 20 to 500 MHz, 500 to 1000 MHz, and 20 to 1000 MHz, these first units offer unrivaled size/power advantages. Specs are guaranteed across full bandwidth and over temperature.
EMC Technology has introduced another cost effective solution for temperature compensation in an SMT planar style, the AN11 series. This ultra mini Thermopad® offers the smallest 0402 package size for temperature variable attenuators in the industry. The AN11 series is perfect for hand held devices and instruments, pico base stations and more. With excellent frequency response from DC to 6 GHz the AN11 series handles 100mW of input power, requires no bias or control voltages and generates zero distortion.
