RF & WirelessComponentsNew 30 W, 32 V, 0.03 - 4 GHzGaN RF TransistorRichardson RFPD, Inc. announced theavailability and full design support capabilitiesfor a new discrete GaN on SiCHEMT from TriQuint/Qorvo. The 30 W(P3dB) TGF3021-SM operates from 0.03to 4 GHz and is constructed with TriQuint’sTQGaN25 production process, which featuresadvanced field plate techniques to optimizepower and efficiency at high drain biasoperating conditions. This optimization canpotentially lower system costs in terms offewer amplifier line-ups and lower thermalmanagement costs.The new transistor is ideally suited formilitary and civilian radar, land mobileand military radio communications, testinstrumentation, wideband and narrowbandamplifiers, and jammer applications. It isavailable in an industry-standard 3x4 mmsurface mount QFN package. According toTriQuint/Qorvo, additional key features ofthe TGF3021-SM include:• output power (P3dB): 36 W at 2 GHz• linear gain: 19.3 dB at 2 GHz• typical PAE (3dB): 72.7% at 2 GHz• operating voltage: 32 V• low thermal resistance package• CW- and pulse-capableNew RF LDMOS WidebandIntegrated Power AmplifiersRichardson RFPD, Inc. announced the availabilityand full design support capabilitiesfor a new LDMOS integrated power amplifierfrom Freescale. The AFIC10275N is theindustry’s first RF power integrated circuitcovering the 978 - 1090 MHz band. It integratestwo amplification stages in a plasticpackage, delivering 250 W with 31 dB ofgain and 64% drain efficiency. The devicealso embeds temperature and RF sensingcapabilities, reducing the need for externalcomponents.The AFIC10275N enables smaller andlighter power amplifier transponders and isdesigned specifically for avionics applications,including air traffic control systemsand ground-based secondary radars, andMode S transponders, including trafficalert and collision avoidance systems andADS-B. It is available as a solution witha reference circuit that reduces cycle timeand develop ment costs for customers. It isavailable in 14-lead and 14-lead gull wingplastic packages. According to Freescale,additional key features of the AFIC10275Ninclude:• on-chip input (50 Ohm) and interstagematching• single-ended• integrated ESD protection• low thermal resistance• integrated quiescent current temperaturecompensation with enable/disable functionNew 2G CDMA Modem forM2M ApplicationsRichardson RFPD, Inc. announced theavailability and full design support capabilitiesfor a new 2G CDMA modem forM2M applications from Maestro WirelessSolutions.The M100CDMAPLUS is partof the Maestro Wireless M100 Series ofcompact, intelligent industrial modems forM2M applications facing tough environmentalconditions and extended lifetimerequirements.
