New GaAs pHEMT semiconductor chips from M/A COM for high-rel comm apps

RF IC chip maker M/A-COM Technology has introduced seven new RF semiconductor chips for networking, aerospace and defense applications.

Here below are the details of the new ICs:

For CATV/Broadband equipment: The MAAM-010263 is a linear 6-way active splitter with low distortion and low noise figure for use in set-top boxes, home gateways and customer premises equipment (CPE) applications. Designed for operation from 50 to 1100 MHz, the amplifier is packaged in a RoHS compliant 4mm 24- Lead PQFN. The 6-way Splitter is fabricated on M/A-COM Tech's E/D pHEMT process.

Also released is the MAAM-010333 , an Optical Node RF Amplifier operating between 50 - 1000 MHz. This integrated TIA, VVA, RF amplifier provides high gain, low 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 4 mm 24-Lead PQFN, and operates between -8 dBm to +2 dBm of Optical input power. With a single +5 V Bias and 27 dB Gain Control Range, the MAAM-010333 is a highly integrated, low cost solution for optical node applications.

RF ICs for cellular Infrastructure: The MAAD-000523 is a 6-Bit, 0.5 dB digital attenuator for 50 ? systems, operating between the 0.7 GHz - 6.0 GHz frequency range. This attenuator is suggestes as ideal when high accuracy, low power consumption, and low intermodulation products are required.

The MAAD-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 4 mm 24-Lead PQFN Package, the MAAD-000523 has small relative phase variation per bit, and achieves an insertion loss of 1.6 dB at 2 GHz. The attenuator features a typical input return loss of 18 dB up to 6 GHz.

M/A-COM Tech has also added two new devices to its family of switches for cellular Infrastructure applications such as base stations. Operating from 0.01 GHz - 4.0 GHz 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.

M/A-COM says with a symmetric circuit design utilizing its GaAs pHEMT technology and an integrated CMOS decoder, both switches maintain 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 cost by replacing multiple single pole double throw (SPDT) switches. These switches suggested as ideal for band switching in multi-channel and multi-mode base-station applications.

Production quantities and samples of the above products are available from stock.
