TGP2108-SM 2.5-4GHz 6-Bit Digital Phase Shifter Product Description The Qorvo TGP2108-SM 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 0 TGP2108-SM offers an exceptional RMS phase error of <2 and amplitude error of <0.4 dB over most of the operational band. With other equally impressive small signal and linearity characteristics, the TGP2108-SM delivers superior performance for your S-band phased array applications. Housed in a small 5 x 5 mm plastic overmold QFN package, DC blocked on both ports with bi-directional operation and the use of positive only control logic, the TGP2108-SM Product Features supports ease of use and simply system integration. Low DC power consumption also provides the system designer Frequency Range: 2.5 to 4 GHz more flexibility in the overall power management of the 6-Bit Digital Phase Shifter system. Bi-Directional 360 Coverage, LSB = 5.625 The device is lead-free and RoHS compliant. RMS Phase Error: < 2 (2.7 3.7 GHz) < 5 (other frequencies) RMS Amplitude Error: < 0.4 dB Insertion Loss: 5 dB Return Loss: 15 dB Input P1dB: 29 dBm Input IP3: 45 dBm Control Voltage: 0 /+3V to +5 V QFN Package Dimensions: 5.0 x 5.0 x 0.85 mm Performance is typical across frequency.
