TQC9307 0.7 4.0 GHz Digital Variable Gain Amplifier General Description The TQC9307 is a digitally controlled variable gain amplifier (DVGA) with a broadband frequency range of 0.7 to 4.0 GHz. The DVGA features high linearity and low noise while providing digital variable gain with a 31 dB of range in 1 dB steps through a serial mode control interface. At 3.5 GHz, the DVGA typically provides 13.3 dB gain, +40.5 dBm OIP3, 32 Pin 5X5 mm leadless SMT Package +21 dBm P1dB and 3.5 dB noise figure. This combination of performance parameters makes the DVGA ideal for receiver applications requiring gain control with high IIP3 Product Features and low noise figure. In addition, the DVGA integrates a shut-down biasing capability to allow for easy operation for Integrates DSA + Amp Functionality TDD applications. 0.7 4.0 GHz Broadband Performance The TQC9307 integrates a high performance digital step 5-bit control, 31 dB range attenuator followed by a high linearity, broadband gain 13.3 dB Gain block. Both stages are internally matched to 50 Ohms and +20.6 dBm P1dB do not require any external matching components. The TQC9307 is packaged in a RoHS-compliant, compact 5x5 +27.7 dBm IIP3, +40.5 dBm OIP3 mm surface-mount leadless package. Integrated on-chip matching, 50 ohm in/out Integrated shutdown control for TDD compatibility +5V Supply Voltage, 3.3V TTL logic compatible Functional Block Diagram Applications Pin 1 Marking Wireless Infrastructure Package Topside LTE / WCDMA / CDMA / GSM 32 31 30 29 28 27 26 25 TDD or FDD systems 1 24 N/C N/C General Purpose Wireless TQC9307 2 23 GND GND RF In 3 22 RF Out/V DSA Amp AMP GND 4 21 GND N/C 5 20 N/C SPI N/C 6 19 N/C 7 18 N/C GND SID 8 17 V PD 9 10 11 12 13 14 15 16 Ordering Information Exposed Backside Pad Part No. Description RF/DC Gnd TQC9307-PCB Evaluation Board Top View TQC9307TR13 2500pcs on a 13 reel Data Sheet February 26, 2018 Subject to change without notice 1 of 9 www.qorvo.com CLK N/C LE N/C GND N/C V N/C DD V N/C DD GND N/C N/C N/C GND N/C TQC9307 0.7 4.0 GHz Digital Variable Gain Amplifier Absolute Maximum Ratings Recommended Operating Conditions Parameter Rating Parameter Min Typ Max Units Storage Temperature -65 to 150 C VAMP +4.75 +5 +5.25 V RF Input Power, CW, 50, 24 hr, 25C +22 dBm V +3 +5 V DD 6 VDD, Power Supply Voltage -0.3 to +5.5 V Tch (for >10 hours MTTF) +190 C Digital Input Voltage -0.3 to V +0.5 V Case Temperature -40 +105 C DD Electrical specifications are measured at specified test Operation of this device outside the parameter ranges given conditions.
