TQL9042

TQL9042 500 – 2000 MHz Bypass LNA Applications Base Station Receivers Tower Mount Amplifiers Repeaters FDD-LTE, TDD-LTE, WCDMA General Purpose Wireless 10-pin 3 x 3 mm DFN Package Product Features 500 – 2000 GHz Operational Bandwidth LNA with Integrated Bypass Mode Ability To Turn LNA and Bypass Mode OFF Ultra Low Noise, 0.42 dB at 900 MHz 19 dB Gain +36 dBm Output IP3 +43 dBm Input IP3 in Bypass Mode Internally Matched Positive Supply Only, +3.3 to +5 V 3 x 3 mm 10-pin DFN Plastic Package General Description The TQL9042 is a high-linearity, ultra-low noise gain block amplifier with a bypass mode functionality integrated in the product. At 900 MHz, the amplifier typically provides 19 dB gain, +36 dBm OIP3, and 0.42 dB noise figure while drawing 70 mA current from a +5 V supply. The component also provides high linearity in the bypass mode with +43 dBm IIP3. The TQL9042 is internally matched using a high performance E-pHEMT process and only requires four external components for operation from a single positive supply: an external RF choke and blocking/bypass capacitors. This low noise amplifier contains an internal active bias to maintain high performance over temperature. The TQL9042 covers the 500 – 2000 MHz frequency band and is targeted for wireless infrastructure. The TQL9042 is packaged in a 3 x 3 mm and is pin compatible with the 1.5 – 2.7 GHz TQL9043 and 1.5 – 2.7 GHz TQL9044. Functional Block Diagram Pin 1 Reference Mark Package Topsi...
