Skywork SKY68011-31 LTE CAT0/CATM1/CATNB1 IoT Module

Skywork SKY68011-31 is a hybrid, multi-band multi-chip RF front-end (RFFE) module supporting cellular LTE for CAT0/CATM1/CATNB1 (half-duplex system) transceiver platforms. The module integrates the entire RF front end necessary for an LTE multi-band radio operating in low-band B12/B13/B17 and mid-band B2/B25/B4/B1/B66 including Rx SAW filters, broadband PA with bias controller, Tx low-pass harmonic filter, antenna switch and MIPI RFFE controller.

Skywork SKY68011-31 functional operation is fully controllable by a single MIPI interface which is used to drive the PA in various optimized bias modes as well as providing band selection and controlling the antenna switch Tx, Rx and band selection.

Skywork SKY68011-31 Features:

* Cost-optimized front end for low-data-rate applications

* Low-loss post-PA transmit front end for enhanced transmitter efficiency (compared to LTE-FDD radio front ends)

* Multi-band PA supporting APT mode of operation or Vcc fixed supply (≥ 2.85 V)

* Integrated low-pass filters for harmonic rejection to comply with spurious emission requirements

* Integrated SP6T antenna Tx/Rx switch

* Integrated Rx SAW filters for out of band rejection for low-band (B12/B13/B17) and mid-band (B2/B25/B4/B1/B66)

* Optimized to support LTE for 1 to 36 RB

* MIPI RFFE control interface, 2.0 compliant

* Pin-to-pin compatible with the SKY68000-31 and SKY68001-31

* Additional Aux port offers greater flexibility for more bands on the Tx or Rx path

* Adaptive biasing scheme for maximum PA efficiencies

* Small, low-profile package (4 mm x 5 mm x 0.9 mm) (MSL3 @ 260 °C per JEDEC J-STD-020)

* Lead (Pb)-free and RoHS-compliant
