PRODUCT SUMMARY SKY68020-11: LTE Universal Multi-Band Front-End Module for IoT Applications Low-power, low-data-rate cellular IoT Half-duplex operation (HD-FDD) LTE: LTE-M NB-IoT LTE universal modem products: Low-band: 5, 8, 12, 13, 14, 17, 18, 19, 20, 26, 28, 71, 85 Mid-band: 1, 2, 3, 4, 25, 39, 66, 70 Features Output power: +24 dBm, optimized to support LTE for 1 RB to 6 RB Exceptional harmonics performance: Figure 1. SKY68020-11 Functional Block Diagram nd Band 13 2 harmonic: -60 dBm/MHz nd Band 28 2 harmonic: -55 dBm/MHz rd Description Band 28 3 harmonic: -52 dBm/MHz The SKY68020-11 is a hybrid, multi-band multi-chip RF front-end Broadband PA supporting APT mode of operation or Vcc fixed (RFFE) module supporting cellular LTE-M/NB-IoT supply: 2.85 V to 4.5 V (half-duplex system) transceiver platforms. The module integrates Integrated Tx low-pass filters for optimized harmonic rejection the entire RF front end necessary for an LTE multi-band radio operating in low-band (5, 8, 12, 13, 14, 17, 18, 19, 20, 26, 28, Integrated SP6T antenna Tx/Rx switch 71, and 85), and mid-band (1, 2, 3, 4, 25, 39, 66, and 70) Integrated Rx low-pass filters for out-of-band rejection frequencies, including Rx low-pass filters, broadband PA with bias Two broadband, high-power AUX ports for additional band controller, Tx low-pass harmonic filter, antenna switch, and MIPI support RFFE controller. Low leakage current: 0.4 uA Tx Section Adaptive biasing scheme for maximum PA efficiencies The PA load-line is optimized for high efficiency while MIPI RFFE control interface, 2.0 compliant simultaneously meeting 3GPP ACLR and emissions mask Pin-to-pin compatible with the SKY68000-31, specifications with LTE up to 6 RB. An integrated LPF is SKY68001-31, and SKY68001-41 implemented to reject the PA and transceiver harmonics while at Operating temperature range: -40C to +85C the same time minimizing any post PA loss for an optimized transmit current consumption. Out-of-band emissions Small, low-profile package (4 mm x 5 mm x 0.9 mm) performance is emphasized by the design to be 3GPP-compliant (MSL3 260 C per JEDEC J-STD-020) for low-band (5, 8, 12, 13, 14, 17, 18, 19, 20, 26, 28, 71, and 85), and mid-band (1, 2, 3, 4, 25, 39, 66, and 70) frequencies.

The filters provide a high level of operation rejection to out-of-band interferers, protecting the transceiver from high blocking signal levels and to support 3GPP LTE Easy programming of fixed-gain steps through the MIPI blocking test conformance. The Rx low-pass filters are cascaded interface with the low throw count switch to establish a lower insertion Reducing the required output dynamic range of the transceiver loss and noise figure than conventional LTE receivers. Auxiliary Paths MIPI RFFE Controller Interface The two AUX ports are additional broadband ports that can be The SKY68020-11 functional operation is fully controllable by a used symmetrically for either Tx or Rx operation. The AUX ports single MIPI interface which is used to drive the PA in various can support conventional GSM power levels. optimized bias modes as well as providing band selection and controlling the antenna switch Tx, Rx, and band selection. Smart Biasing For most IoT applications, the DC-DC converter might not be available to control the VCC supply of the PA. With a fixed DC Figure 1 shows the block diagram for the SKY68020-11. supply, Smart Biasing allows for easy power control through the MIPI interface by programming reduced bias current for lower gain states. Based on the application, a set of 4 to 6 different bias conditions with specific fixed-gain steps are predefined. For each of the steps, the transceiver output power can be adjusted to meet the desired total output power.
