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.
Linear Technology announces the LTC6433-15, a wideband 15 dB gain block amplifier offering outstanding linearity of 47 dBm OIP3 (output third order intercept) and 3.22 dB noise figure at 150 MHz. The amplifier has excellent OP1dB (output 1dB compression point) of 19.2 dBm. The LTC6433-15 is uniquely different from other gain block amplifiers that are typically built using GaAs or pHEMT processes. These FET technologies have high 1/f noise corners on the order of 20 to 30 MHz.
RFMW Ltd. announces design and sales support for the RF circulator isolator, (RFCI) model RFCR8801 circulator. The RFCR8801 covers the full S-band (2-4GHz) in a drop-in package configuration. Broadband performance is outstanding with typical insertion loss <0.5 dB and >19 dB isolation. Forward power handling is rated at 50 W average and 500 W peak. Reverse power handling is 30 W CW.
AtlanTecRF launched a range of dual channel loop test translators designed to provide a comprehensive test and quality monitoring facility in satellite communications ground stations and teleports. The ALD series of LTTs, available for operation in both Ka and Ku bands, feature simultaneous translation of transmit (Tx) frequencies to L-band and L-band to receive (Rx) frequencies thereby enabling uplink and downlink parameters to be evaluated at the same time and with one instrument.
Rogers Corp. introduces RO4730G3™ UL 94 V-0 antenna-grade laminates to meet present and future performance requirements in active antenna arrays and small cells, notably in 4G base transceiver stations (BTS) and Internet of Things (IoT) applications as well as emerging 5G wireless systems.These flame-retardant (per UL 94V-0), thermoset laminate materials are an extension of Rogers’ dependable RO4000® circuit materials.
The release of a line of arbitrary waveform generators based on the LXI instrumentation standard, opens the door for engineers and scientists who need to generate electronic signals in automated test and remote applications. Spectrum has released seven instruments in the generatorNETBOX series. The units combine the latest digital-to-analog converter technology and can generate signals from DC up to 400 MHz in frequency.
Richardson RFPD Inc. announced the availability from stock and full design support capabilities for a fastPack 0 SiC power module from Vincotech. The 10-PC094PB065ME01-L637F06Y is a faster, cooler and more efficient power module designed for switching frequencies up to 400 kHz. It features a fast-switching 900 V SiC MOSFET that outperforms 1200 V SiC MOSFETs (+8% efficiency at a light load and +3% at full load) and provides a higher safety margin than 650 V MOSFETs.
Pasternack debuts lines of waveguide bends operating from 5.85 to 90 GHz across 12 frequency bands (from C band to W band). These waveguide bends are commonly used in applications such as instrumentation, test benches, high efficiency RF, microwave and mm-wave transmissions, SATCOM, MILCOM, radar and telecom. Pasternack’s in-stock and ready-to-ship waveguide bends boast low loss and VSWR as low as 1.08:1.
RFMW Ltd. announces design and sales support for the API Weinschel 7006-1 DC block. The 7006-1 is an ‘inside’ DC block containing capacitance in-series with the center conductor to prevent the flow of DC current while permitting RF power to flow uninterrupted. The 7006-1 passes RF from 9 kHz to 20 GHz with an SWR of 1.3:1. API Weinschel rates the power handling at 20 W averages and 100 W peak. Maximum DC voltage is 50 V.
JQL Electronics introduces a high performance SMT millimeter wave circulator / isolator series designed for 5G network. The SMT microstrip solutions are true surface mount with no need of any additional biased steel plate for installation. The solution covers 18, 28 and 40 GHz bands, with up to 20 dB isolation, 0.7 dB insertion loss. Custom design microstrip isolators / circulator is available from 5 to 40 Ghz.
The OX-400/401 and the MD-403 are the latest additions to the OCXO extended temperature range product family. Stabilities of +/-5 ppb (OX-400/401) and an uncorrected stability of +/-10 ppb (MD-403) are achieved while operating across a temperature range of -40° to 95°C. These OCXOs are ideal for applications in uncontrolled environments where operating temperatures can exceed the industrial temperature range.
