TriQuint's multipurpose gain block family expands
The devices employ the firm's high reliability indium gallium phosphide / gallium arsenide HBT process technology. They are particularly suited to commercial and defence applications
TriQuint Semiconductor has added the TQP369185 device to its family of broadband, cascadable Darlington-pair amplifier RFICs that operate from DC to 6 GHz.
Claimed to have excellent efficiency, they deliver strong performance as general-purpose gain blocks for IF and RF buffer gain stages in commercial and defence applications ranging from base station transceivers (BSTs) and repeaters to CATV and SATV systems, test equipment and numerous other RF and microwave systems.
The new InGaP/GaAs HBT gain block RFICs include the TQP369180 and TQP369181 that deliver 15 dB of ultra-flat gain and the TQP369182 and TQP369184 that deliver 20 dB of gain. Both 15 dB gain and 20 dB gain models are available in a choice of two.
The latest addition to the family, TQP369185, offers up 20.5 dB of gain and up to 19.7 dBm of P1dB and also integrates an internal active bias.
All are internally matched to 50 Ω, requiring only an external RF choke, dropping resistor, and blocking/bypass capacitors for operation. TriQuint says they are also are very rugged, meeting Class 1C HBM (up to 2 kV) electrostatic discharge (ESD) requirements.
Gain blocks are some of the most widely used active components in all types of RF and microwave systems, and they must combine excellent performance with very good cost efficiency.
TriQuint says its five new devices meet these requirements and are available in two plastic package styles. They offer a choice of gain levels that the firm says, meet almost any design need, whilst consuming minimal power. Their broad frequency range makes them well suited for many applications through 6 GHz.
The new Darlington-pair gain block RFICs are now in production. Samples, evaluation boards and software are also available.
