Ted Rappaport, founding director of NYU WIRELESS and a leading proponent of using the millimeter wave spectrum for wireless communications, discusses the FCC's recent rulemaking actions and technology developments that are paving the way to 5G.
AtlanTecRF introduced a concept in the application and use of satellite communications Loop Test Translators, a series of instruments designed to be portable rather than part of a permanent 19” rack installation. The new BLT range, covering S, C, X, Ku, DBS and Ka bands, feature the portable bench instrument style housing allowing the units to be readily moved between test locations.
Vaunix Technology Corp., a manufacturer of USB controlled and powered test equipment, recently added a programmable digital attenuator to their LDA family of PC-driven Lab Bricks, the LDA-602EH. The LDA-602EH has a large attenuation range of 120 dB with an exceptional 0.1 dB step size, allowing for both precision and accuracy during fading tests or device characterizations. This attenuator also features a fast 15 µs switching speed.
MECA’s low PIM (-165 dBc Typ) adapters for DAS applications feature industry leading PIM performance of -160 dBc Min. Available in 7/16 DIN, Type N, SMA and 4.1/9.5 standard and bulkhead connectors. Ideal for IDAS / ODAS, in-building, base station, wireless infrastructure, 4G and 5G applications.
Analog Devices Inc. introduced a low power, high performance, radio transceiver for battery powered applications. The transceiver enables more reliable wireless radio connections with fewer retries and packet losses as well as longer battery lifetime. The ADF7030-1 features a highly sensitive receiver and superior immunity to signal interference as well as low power modes, including the industry’s lowest current in sleep mode.
RFMW Ltd. announces design and sales support for a dual, low noise amplifier (LNA) from Qorvo. The TQL9066 incorporates two, matched, E-pHEMT LNAs enabling balanced amplifier configurations with noise figure rated at 0.6 dB. Applicable for the first stage in receivers, the Qorvo TQL9066 finds homes in BTS transceivers, L-Band radios and tower mounted amplifiers operating from 0.05 to 1.5 GHz.
Anritsu Co. expands its Signal Analyzer MS2840A family with the introduction of three models that support the 9 kHz to 3.6 GHz, 6 GHz, and 26.5 GHz frequencies. With the instruments, Anritsu fills a market void for cost-efficient, high-performance signal analyzers that address the middle frequency ranges, providing an economical solution to accurately measure wireless equipment, oscillators and other components for narrowband applications, and more.
Richardson RFPD Inc. announced the availability and full design support capabilities for a 100 W continuous wave SPDT reflective switch from Microsemi Corporation. The MPS2R10-606 SPDT series-shunt PIN diode switch operates from 50 to 1000 MHz, with 500 ns switching speed. At 100 MHz, it typically offers 60 dB isolation, with 0.1 dB insertion loss and 28 dB return loss. At 500 MHz, it typically offers 55 dB isolation, 0.2 dB insertion loss, and 15 dB return loss.
MECA is pleased to announce its latest addition to our extensive line of stripline couplers with the 780-dB-9.500-M01, covering from 1.0 to 18.0 GHz. Available in 10 and 20 dB models with SMA female connectors, optimized for excellent performance with industry leading specifications offering typical VSWR’s ranging from 1.40:1, isolation of 15 dB typical.
QMA power divider/combiners, 2-Way through 8-Way, 40 W power divider/combiners are optimized for excellent performance across all wireless bands from 698 MHz to 2.7 GHz. Ideal for IDAS / ODAS, in-building, base station, wireless infrastructure, 4G and 5G applications. Rack mount versions also available. Additionally, MECA also offers QMA Attenuators and Terminations.
2-Way & 4-Way, 30 W Wilkinson power dividers with industry leading spec’s across Microwave and Millimeter-wave bands covering 6.0 to 40.0 GHz with 2.92 mmconnectors. The 2-way has typical numbers of; 1.3:1 input and 1.17:1 output VSWR’s and isolation of 22 dB Typ. The 4-way also has excellent typical spec’s of 1.2:1 VSWR’s and isolation of 19 dB Typ.
