QPC6144

The QPC6144 is a silicon-on-insulator SP4T switch from Qorvo for test equipment, base-station and general RF routing from 50 MHz to 12 GHz, with electrical specifications characterised across 0.05 GHz to 10 GHz. Its headline figure is isolation: 89 dB from RFC to an off port at low band and still above 65 dB at 8.6 GHz to 10 GHz, so a single device can replace cascaded switch stages in high-dynamic-range signal paths. Insertion loss runs from 0.85 dB at low band to 1.50 dB at the top band, input IP3 is +57 dBm typical, off ports are terminated in 50 ohm (non-reflective), and the RF pins need no DC blocking capacitors when no external DC is applied. Control logic is selectable for 1.2 V, 1.5 V or 1.8 V JEDEC levels, an integrated negative-voltage generator allows single-supply operation, and the supply spans 3.15 V to 5.5 V. It is housed in a 4 x 4 mm 24-pin leadless package rated to +115 C case temperature. Selection advice: verify your highest operating frequency against the characterised 10 GHz specification limit rather than the 12 GHz headline range before committing the design. Parameters verified against Qorvo documentation.
