Technical Description The SKY65329-NP provides input and output amplifier stages and is internally matched for optimum efficiency. An active bias circuit provides both input and output stages with excellent gain tracking over temperature and voltage variations. The module operates with positive DC voltages, and maintains high efficiency and good linearity. The nominal operating voltage is 3.6 V for maximum power, but the device can be operated at slightly lower voltages for other mobile applications. Operational Modes By using three control signals (CTRL1, CTRL2, and PWR_DOWN), the module can be configured to one of five operational modes: Auxiliary power. In this mode, the PA and LNA are off and the VDD_OUT signal (pin 26) can be used for auxiliary power, which can supply up to 10 mA of VDD power to external circuitry. 900 MHz receive. In this mode, the SKY65329-NP amplifies the received signal at the antenna port through the LNA. 900 MHz transmit. In this mode, the transmit path provides an harmonic filter and high efficiency PA. Auxiliary RF bypass. In this mode, a low-loss broadband bidirectional RF path allows easy switching of the signal between the transceiver and the antenna port. Power down. In this mode, the PA and LNA are powered down for minimal current consumption and low leakage current (5 μA). Table 1 provides the control logic for each of the five operational modes. |
