QPC2108 2.5-4GHz 6-Bit Digital Phase Shifter Product Description The Qorvo QPC2108 is a packaged 6-bit digital phase shifter fabricated on Qorvos high performance 0.15 um GaAs pHEMT process. It operates over 2.5-4 GHz while providing 360 of phase coverage with a LSB of 5.625. The QPC2108 offers an exceptional RMS phase error of <2.8 degrees and amplitude error of <0.4 dB over most of the operational band. With other equally impressive small signal and linearity characteristics, the QPC2108 delivers superior performance for your S-band phased array applications. Product Features Housed in a small 6 x 6 mm plastic overmold QFN package, DC blocked on both ports with bi-directional operation and Frequency Range: 2.5 to 4 GHz the use of positive only control logic, the QPC2108 supports 6-Bit Digital Phase Shifter ease of use and simply system integration. Low DC power Bi-Directional consumption also provides the system designer more 360 Coverage, LSB = 5.625 flexibility in the overall power management of the system. RMS Phase Error: < 2.8 (2.5 3.8 GHz) The device is lead-free and RoHS compliant. < 5 (3.9 4 GHz) RMS Amplitude Error: < 0.4 dB Evaluation Boards are available upon request. Insertion Loss: 5 dB Return Loss: 16 dB Input P : 23 dBm 0.1dB Input IP3: 45 dBm Switching Speed: < 100 ns Control Voltage: 0 /+5 V QFN Package Dimensions: 6.0 x 6.0 x 0.79 mm Performance is typical across frequency.
