23 January 2012 M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes analog semiconductors, components and subassemblies for RF, microwave and millimeter-wave applications) has launched seven new products covering networks and aerospace & defense applications. For CATV/broadband, the MAAM-010263 completes M/A-COM Tech’s family of default-on broadband active splitters designed for multi-tuner set-top boxes, home gateways and customer premises equipment (CPE) applications. Featuring a default-on loop-through path, the MAAM-010263 allows for access to the cable signal even when the CPE box is powered down. The device is a highly linear 6-way active splitter with low distortion and low noise figure. Designed for operation from 50 to 1100MHz, the amplifier is packaged in a RoHS compliant 4mm 24-lead PQFN. The 6-way Splitter is fabricated on M/A-COM Tech’s established E/D pHEMT process which delivers , low distortion, low noise figure and highly repeatable performance . Also released is the MAAM-010333, an optical node RF amplifier operating at 50–1000MHz. The integrated TIA, VVA, RF amplifier provides high gain, low equivalent input noise (EIN), and low distortion amplification for optical node applications. Fabricated on M/A-COM Tech’s GaAs pHEMT technology, the amplifier is packaged in a 4mm 24-lead PQFN, and operates between –8dBm to +2dBm of optical input power. With a single +5V bias and 27dB gain control range, the MAAM-010333 is a highly integrated, low-cost solution for optical node applications, says M/A-COM Tech. For cellular infrastructure, the MAAM-000523 is a 6-bit, 0.5dB digital attenuator for 50O systems, operating in the 0.7–6GHz frequency range. The attenuator is suitable for when high accuracy, low power consumption and low intermodulation products are required. The MAAM-000523 includes an integrated TTL/CMOS-compatible driver, and offers parallel and serial control with a power-up state function. Packaged in a lead-free 4mm 24-lead PQFN, it has small relative phase variation per bit, and achieves an insertion loss of 1.6dB at 2GHz. The attenuator features a typical input return loss of 18dB up to 6GHz. M/A-COM Tech has also launched two new additions to its family of switches for cellular infrastructure applications. Operating at 0.01–4.0GHz and packaged in an industry-standard 4mm 24-lead PQFN, the MASW-010350 is a high-isolation single-pole four-throw (SP4T) switch, while the MASW-010351 is a high-isolation single-pole five-throw (SP5T) switch. With a symmetric circuit design using M/A-COM Tech’s GaAs pHEMT technology and an integrated CMOS decoder, both switches maintain what is claimed to be an excellent combination of low insertion loss and high isolation for all states. The new switches are designed to lower the system complexity and reduce the bill of material (BoM) cost by replacing multiple single-pole double-throw (SPDT) switches. The switches are suitable for band switching in multi-channel and multi-mode base-station applications. For aerospace & defense, the 8–12GHz MAPS-010146 and MAPS-010166 are X-band additions to M/A-COM Tech’s family of The MAPS-010146 is a 4-bit digital phase shifter that provides 360 The MAPS-010166 is a 6-bit digital phase shifter that provides 360° phase shift range with a step size of 5.625°. Insertion loss is 6.5dB, with a low +/-1.2dB attenuation variation and +/-8.0° phase accuracy. Both are housed in a 4mm 24-lead PQFN package, and are controlled with a single +5V serial or parallel control line. Production quantities and samples of the above products are available from stock..
