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.
Custom MMIC is pleased to announce a GaAs MMIC frequency doubler, the CMD225C3. The released CMD225C3 operates with an input frequency range of 4 to 8 GHz. This passive frequency doubler can be driven with a +15 dBm input signal with a low conversion loss of 13 dB, and excellent Fo and 3 Fo isolations of at least 47 dBc. THe CMD225C3 is a 50 ohm matched design to eliminate the need for RF port matching.

Spectrum’s M4x series of PXIe Arbitrary Waveform Generators offer a cost effective solution for automated testing applications that require fast and accurate electronic signal generation. Based on the modular PXIe instrumentation standard, the M4x series includes five new modules that provide one, two or four channels. Each channel is equipped with the latest 16 bit digital-to-analog converter technology.
RFMW Ltd. announces design and sales support for a surface mount GaN power amplifier from Qorvo. The Qorvo TGA2830-SM offers 18 W of saturated output power from 2.7 to 3.5 GHz. Small signal gain is >30.5 dB and input return loss is rated at >11 dB. The TGA2830-SM draws 225 mA from a 20 to 32 V bias supply with >54% power added efficiency (PAE).
Richardson RFPD Inc. announced the availability and full design support capabilities for a new bi-directional surface-mount coupler from Innovative Power Products, Inc. The IPP-8036 is one of the featured surface-mount products from IPP’s full line of dual directional couplers. It is a 300 W, 50 dB dual directional coupler that operates from 20 MHz to 1000 MHz.
RFMW Ltd. announces design and sales support for a 2-stage low noise amplifier (LNA) with integrated bypass switch in the second stage. Operating from 1.5 to 3.8 GHz, the Qorvo TQL9065 provides 0.5 dB noise figure and up to 36 dB of gain through the internal amplifiers. When gain is not needed, the bypass switch automatically turns off the LNA for power savings.
