TQC9311 0.4 3.8 GHz Dual Channel DVGA RFMD + TriQuint = Qorvo Applications Wireless Infrastructure LTE / WCDMA / CDMA / GSM General Purpose Wireless Diversity or MIMO Receivers 32-pin 7x7mm Leadless SMT Package Product Features Functional Block Diagram 32 31 30 29 28 27 26 25 Dual channel, integrating DSA + Amp Functionality 1 24 0.4 3.8GHz Broadband Performance 2 23 13.2dB Gain at 1.95GHz DSA AMP1 3.8dB Noise Figure at max gain setting 3 22 +21.1dBm P1dB 4 21 12-bit +36.5dBm OIP3 SPI 5 20 +5V Supply Voltage Integrated on-chip matching and bias chokes 6 19 3-wire SPI Control Programming AMP2 DSA 7 18 +1.8V and +3.3V logic compatible serial input 8 17 10 12 13 14 15 16 9 11 Pin Configuration General Description The TQC9311 is a dual-channel, digitally-controlled Pin No. Label Pin No. Label variable gain amplifier (DVGA) operating over a 1 RFIN 1 8 RFIN 2 broadband frequency range of 400 to 3800 MHz. The 3 VCC SPI 15 VDD AMP2 DVGA features +36.5 dBm OIP3 while providing digital 4 LE 17 RFOUT 2 variable gain with 31.5 dB of gain range in 0.5 dB steps 5 DATA 24 RF OUT1 through a 12-bit serial mode control interface. This 6 CLK 26 VDD AMP1 combination of performance parameters makes the 7, 10, 13, 28, 31 No Connect 26 VDD AMP1 DVGA ideal for diversity or MIMO receiver applications requiring gain control with high linearity and low noise All other pins are internally grounded. figure. The TQC9311 integrates a high performance digital step attenuator followed by a high linearity, broadband gain block in a dual-channel configuration. The dual channel DVGA is internally matched to 50 Ohms and does not require any external matching components. Bias choke inductors and bypass/blocking capacitors are also integrated into the module thereby reducing the number Ordering Information of external components needed. Part No. Description The TQC9311 is packaged in a RoHS-compliant, TQC9311 0.4-3.8 GHz Dual-channel DVGA compact 7x7 mm surface-mount leadless package. TQC9311-PCB Evaluation Board Standard T/R size = 2500 pcs on a 13 reel.
