TriQuint adds five new 6GHz cascadable Darlington-pair amplifier RFICs

RF front-end component maker and foundry services provider TriQuint Semiconductor Inc of Hillsboro, OR, USA has launched a family of broadband, cascadable Darlington-pair amplifier RFICs that operate from DC to 6GHz, for use as general-purpose gain blocks for IF and RF buffer gain stages in commercial and defense applications ranging from base-station transceivers and repeaters to CATV and SATV systems, test equipment and other RF and microwave systems.

The new InGaP/GaAs HBT gain block RFICs include the TQP369180 and TQP369181 (which deliver 15dB of ultra-flat gain) and the TQP369182 and TQP369184 (which deliver 20dB of gain). Both 15dB-gain and 20dB-gain models are available in a choice of two inexpensive plastic packages (SOT-89 or SOT-363). The latest addition to the family, TQP3691805, offers up 20.5dB of gain and up to 19.7dBm of P1dB, and also integrates an internal active bias. All are internally matched to 50 Ohms, requiring only an external RF choke, dropping resistor, and blocking/bypass capacitors for operation. They are also rugged, meeting Class 1C HBM (up to 2kV) electrostatic discharge (ESD) requirements.

Gain blocks are some of the most widely used active components in all types of RF and microwave systems, and must combine performance with good cost efficiency, says TriQuint. The firm says that the five new devices meet these requirements in two package styles and a choice of gain levels that meet almost any design need, all while consuming minimal power. Their broad frequency range makes them suited to most applications through 6GHz.

All five of the new gain blocks are InGaP/GaAs HBT Darlington-pair cascadable gain RFICs that support DC to 6GHz.

Samples, evaluation boards and software are now available for the five new Darlington-pair gain block RFICs.
