GaAs MMIC Devices

Freescale Semiconductor entered the GaAs MMIC marketplace with the introduction of four new devices designed and optimized specifically for high performance in macro base stations, repeaters and femtocells employed in wireless networks. The devices address low-noise amplifiers and transmit power amplifiers, two elements of wireless infrastructure equipment for which extremely high RF performance is critical. The devices are also designed for low power consumption, resulting in optimized energy efficiency and long-term reliability.

THz Schottky Barrier Diode Foundry Process

The planar Schottky diode process features cutoff frequency (fco) > 1 THz with an ideality factor of 1.1. The low diode turn-on voltage (< 500 mv) allows mixer operation with a LO power below 10 dBm and a conversion loss of 6.5 dB at W-band. GCS's process can be integrated with other passive components, such as MIM caps, spiral inductors, thin film resistors and transmission lines to realize diplexers and filters monolithically. The monolithic integration eliminates unwanted parasitic elements from wire bond, which is highly undesirable at mmW frequencies. For microwave frequency transceiver components, this THz diode is ideal for low conversion loss mixers, with options to be monolithically integrated with HBT circuits (LO and linear PA) and HEMT circuits (LNA, switch and PA).

Sub-harmonic SMT MMIC Upconverter

The HMC711LC5 is a GaAs MMIC Sub-harmonic upconverter that delivers a small-signal conversion gain of 15 dB and wide IF bandwidth of DC to 3.5 GHz. The HMC711LC5 utilizes a double-balanced mixer that is driven by an active x2 multiplier and followed by a high linearity amplifier. This compact upconverter accepts LO input frequencies from 9.5 to 13.6 GHz, and LO power levels as low as 0 dBm, allowing it to be driven directly from a synthesizer output. The HMC711LC5 also exhibits +28 dBm output IP3 and +17 dBm output P1dB, and operates from a single +5 V supply. This high linearity converter is a much smaller alternative to hybrid style sub-harmonic upconverter assemblies and eliminates the need for wire bonding by allowing the use of surface-mount manufacturing techniques.

Injector-Diplexer

Microlab announced a new low cost injector-diplexer, to separate or combine the VHF-UHF band from 80 to 520 MHz from all the wireless frequency bands from 698 to 2700 MHz. Using suspended substrate, the wireless frequency loss is minimized to less than 0.5 dB, and the loss at VHF-UHF frequencies is less than 0.3 dB. "Tuned-by-Design" eliminates the high cost of adjusting multiple cavities in conventional designs, while maintaining high isolation between key bands, sufficient for most diplexer applications, such as sharing a common antenna or distributed antenna system.
