PIN diode switches feature high port-to-port isolation
A family of PIN diode switches, featuring high port-to-port isolation, has been introduced by Pasternack Enterprises. With a frequency range of 1-12GHz, the switches provide port-to-port isolation of more than 90dB at 1-2GHz, 80dB at 2-4GHz and 75dB at 6-12GHz. Depending on the frequency, insertion loss varies between 1.0dB and 2.5dB and switching speed between 35 and 75ns.
Clock synthesiser targets comms & industrial applications
Expanding its universal clock portfolio, Exar has announced the XR81112 series suited for demanding communications, audio/video and industrial applications. The clock synthesiser provides 10MHz to 1.5GHz output frequencies with ultra-low phase noise jitter of less than 200fs.
'Industry's first' plastic-housed amplifiers with VSWR >65:1
The MRFE6VP5150 and MRFE6VP5300, plastic packaged power amplifiers designed for harsh environments, has been introduced by Freescale Semiconductor. These amplifiers are claimed to be the industry’s first devices to be housed in over molded plastic packaging with a VSWR rating of more than 65:1.
Coaxial termination ensures secure mechanical attachment
A medium-power coaxial termination, suitable for use in HF and VHF systems in demanding environments, has been released by Link Microtek. The AMCOL-1-T, which absorbs RF signals in the frequency range of 10-100MHz, is fitted with a TNC male connector incorporating a coarse-ribbed M27-threaded collar to ensure secure mechanical attachment.
Digital attenuator offered as bare die or in PQFN package
Richardson RFPD has availability and full design support capabilities for a new wideband, 6-bit digital attenuator from M/A-COM Technology Solutions. The MAAD-011021 is offered in both bare die and in a 3 mm PQFN package, operating from DC–40 GHz (an industry first for a 6-bit digital attenuator) and DC–30 GHz, respectively.
RF power solutions target advanced wireless infrastructure
Freescale Semiconductor has announced 2nd gen Airfast RF power solutions. The company has claimed that this generation of devices deliver a new level of performance for advanced wireless infrastructure equipment, including GSM/UMTS, CDMA/W-CDMA, LTE, and TD-LTE applications.
2W power amplifier reduces design time and costs
Covering all frequency bands between 1500 and 2700MHz, the MMZ25333B 2W integrated power amplifier has been introduced by Freescale. The amplifiers operate with a 5V supply and deliver more than 40dB of gain, supporting any cellular standard operating at this frequency - including GSM, 3G, 4G and LTE.
VCO operates across 200-239MHz frequency range
The CVCO55FL-0200-0239, a VCO which operates across a 200-239MHz frequency range with a control voltage range of 0.5-4.5V, has been introduced by Crystek. This features a typical phase noise of -123dBc/Hz at 10KHz offset and has an output power of +8.5 dBm.
Family of 25, 50 and 100W attenuators are introduced
A family of 25W, 50W and 100W attenuators have been introduced by Fairview Microwave. The family, numbering 236 devices, feature 3, 6, 10, 20, 30, 40, 50 and 60dB attenuation options, and can be ordered with SMA, TNC, Type-N and 7/16 DIN in-series connector configurations. The attenuators also come in each gender interface, including male-male, male-female and female-female.
SDR prototyping kit allows for multi-channel synchronisation
A SDR rapid prototyping kit, billed as the industry’s first, has been released by Analog Devices. Incorporating dual 2 x 2 AD9361 RF transceivers, the AD-FMCOMMS5-EBZ kit aims to simplify and rapidly prototype 4 x 4 MIMO wireless transceiver applications on the Xilinx Zynq-7000 all programmable SoC development platforms.
