The BFQ790 is a single stage driver amplifier with very high linearity. Its output 1dB compression point is 27 dBm. The device is housed in the halogen-free industry standard package SOT89. The high thermal conductivity of silicon substrate and the low thermal resistance of the package add up to a thermal resistance of only 35 K/W, which leads to moderate junction temperatures even at high dissipated power values. The proper die attach with good thermal contact is 100% tested to ensure the thermal properties. The device is based on Infineon's reliable and cost effective NPN SiGe technology running in high volume. The collector design allows safe operation with 5 V supply voltage. The BFQ790 is very rugged. A special collector design prevents from thermal runaway respectively 2nd breakdown, which leads to a high ruggedness against mismatch at the output. The special design of the emitter/base diode makes it robust and yields to a high maximum RF input power capability. | Summary of Features: High 3rd order intercept point OIP3 of 41 dBm @ 5 V, 250 mA in 1850 MHz and 2650 MHz Class A application circuits; High compression point OP1dB of 27 dBm @ 5 V, 250 mA corresponding to 40% collector efficiency; High power gain of 17 dB @ 5V, 250 mA in 1850 MHz Class A application circuit; Low minimum noise figure of 2.6 dB @ 1800 MHz, 5 V, 70 mA; Single stage, intended for external matching; Exceptional ruggedness up to VSWR 10:1 at output; High maximum RF input power PRFinmax of 18 dBm; Safe operation with single 5 V supply; 100% test of proper die attach for reproducible thermal contact; 100% DC and RF tested; Easy to use large signal compact (VBIC) model available; In-house NPN SiGe technology running in very high volume; Easy to use Pb-free (RoHS compliant) and halogen-free industry standard package SOT89, low RTHJS of 35 K/W | Target Applications: High linearity driver or pre-driver in the transmit chain; 2nd or 3rd stage LNA in the receive chain; IF or LO buffer amplifier; Commercial / industrial wireless infrastructure / Base stations / Small cells; Repeaters; Automated test equipment
