Custom MMIC's GaAs MMIC frequency multipliers span 8 to 40 GHz

Custom MMIC, a leading developer of performance-driven monolithic microwave integrated circuits (MMICs), has expanded its standard product portfolio with three new frequency multipliers/doublers. The multiplier family now covers output frequencies from 8 to 40 GHz, with both passive and active architectures. The active multipliers offer high output power for driving mixers directly, while their passive counterparts offer low phase noise with a lower output power.

TRAK Microwave's GaN SSPA powers Ku band block upconverter

 The model MFC147 from TRAK Microwave provides 13.75 to 14.50 GHz coverage for civilian and military aviation Ku-band SATCOM applications, including In-Flight Entertainment (IFE) systems and UAV communications. The unit features a ruggedized design and innovative thermal management technique to withstand challenging airborne environments utilizing SMT construction with no open die. Input frequency to the Block Upconverter (BUC) is 950-1700 MHz, with Ku-band output of +12 to +17 dBm.  An integrated, low-noise, GaN, Solid State Power Amplifier (SSPA) provides 25 watts minimum output power providing better than -120 dBc/Hz noise power (-140 dBc/Hz typical) and <-22 dBc spectral regrowth (OQPSK).

Linear's synchronous forward MOSFET driver eliminates signal transformer

Linear Technology Corp. announces the LT8311, a high efficiency secondary-side MOSFET driver that operates without the need for primary control in an isolated synchronous forward converter. The LT8311’s unique preactive mode eliminates the need for a signal transformer for primary to secondary-side communication by sensing signals on the secondary side to control synchronous rectification. This mode reduces component count and solution size.
