The Lab-Flex® product…
Skyworks high power switches offer transmit/receive and failsafe switching for TDD-LTE, TD-SCDMA, base station, repeater, and military low frequency radio applications. These PIN diode-based switches will handle 40 W and up to 100 W of CW RF input power at 25 degrees C. A small 4×4 mm QFN plastic surface mount technology (SMT) package is ideal for compact system designs with challenging power levels. Low insertion loss minimizes receiver noise figure while high isolation provides protection to the receiver during large transmitter output signals. Skyworks SKY12212-478LF handles up to 100W CW from 50 to 2700 MHz with an insertion loss…
RFaxis, a leading manufacturer of RF Front-end ICs (RFeIC) offers three new porfolio brochures detailing the features and benefits of their single-chip/single-die CMOS products. The RFeIC has fundamental advantages over Front-end Modules (FEMs) in that a fully integrated CMOS IC is lower cost and has a smaller footprint than a comparable front-end “module” containing multiple devices. The RFaxis Smart Energy/Smart Home, ZIGBEE and ISM brochure highlights the use of the RFX2401C, RFX1010 and RFX2411 in these applications. Their WLAN in Mobile Devices brochure reviews infotainment applications and the WLAN Computing & Infrastructure covers access points and router applications. The RFaxis…
RFMW, Ltd. announces design and sales support for TriQuint Semiconductor BAW filters including the 885025, a Band 2 uplink filter at 1880MHz. BAW filters offer improved power handling performance over traditional SAW filters. The TriQuint 885025 has a usable bandwidth of 60MHz and the RoHS compliant 3x3mm ceramic package can handle up to 1W (30dBm) of CW RF energy. The associated chart shows two additional TriQuint BAW filters, the 885024, Band 2 downlink filter and the 885009, Band 7 uplink filter. All three filters boast low insertion loss and high out-of-band attenuation. Single ended operation at 50 ohms requires no…
RFMW, Ltd. announces design and sales support for Johanson Technology’s (JTI) newly introduced 2450BP15Q0100, 2.4GHz, High-Rejection Band Pass Filter (BPF) with Land Grid Array (LGA)-type terminations. This brand new BPF has the highest close-to-passband rejection with the smallest footprint ever made by JTI. With a 3dB bandwidth of 100MHz centered at 2.45GHz, minimum attenuation of the JTI 2450BP15Q0100 at 2170MHz is 30dB, yet maximum passband insertion loss is 1.8dB at 25° C. The 0805 package incorporates an LGA termination for reduced real-estate usage and can handle up to 2W. The JTI 2450BP15Q0100 is targeted towards low cost WiFi applications where…
RFMW, Ltd. announces design and sales support for TriQuint Semiconductor’s TQP4M0010, SPDT switch featuring up to 50dB of isolation from an internally terminated, absorptive design. This new TriQuint switch includes an internal decoder and offers a single, positive voltage control of 1.8 to 5V. Operating from 100MHz to 4.5GHz, the TriQuint TQP4M0010 is ideal for 3G/4G wireless infrastructure and small cell applications as well as T&M and Defense applications where low insertion loss of 0.55dB is a requirement. The TQP4M0010 does not need any external matching components, making it an easy-to-use device in a standard QFN 4x4mm package.
