SKY66430-11
LTE for IoT System-in-Package

The SKY66430-11 is a multi-band multi-chip System-in- Package (SiP) supporting cellular LTE-M/NB-IoT (half-duplex FDD) platforms. The SiP integrates the entire RF front end, transceiver, power management, memory, and baseband modem for an LTE multi-band radio operating in the 700 to 2200 MHz frequency range. NOR flash, crystals, and a few passives external to the package complete the SiP implementation.

Front-End Section

The front-end section includes Rx low-pass filters, broadband PA with bias controller, Tx low-pass harmonic filter, and antenna switch.

Rx Section

Receive low-pass filters are integrated into the SIP along with the necessary matching to yield a 50 Ωsingle-ended impedance for the antenna. The filters provide a high level of rejection to out-of-band interferers, protecting the transceiver from high blocking signal levels and guaranteeing 3GPP LTE blocking test conformance. The Rx low-pass filters are cascaded with the low throw count switch to establish a lower insertion loss and noise figure than conventional LTE receivers.

Tx Section

The PA load-line is optimized for high efficiency while simultaneously meeting 3GPP ACLR and emissions mask specifications with LTE up to 6 RB. An integrated LPF is implemented to reject the PA and transceiver harmonics while at the same time minimizing any post PA loss for an optimized transmit current consumption. Out-of-band emissions performance is emphasized by the design to be 3GPP-compliant for B5/B8/B12/B13/B14/B17/B18/B19/B20/B26/B28 and midband B1/B2/B3/B4/B25/B66.
