摘要： A system, apparatus and method for providing filtering functionality and impedance transformation within a BAW resonator network are disclosed. In particular, a BAW resonator network is designed to provide bandpass capability and a transformation between its input impedance and output impedance. By effectively integrating impedance matching functionality within the BAW resonator network, discrete impedance matching elements previously required within a system may be removed or reduced in size. As a result, matching networks and their associated component costs, insertion losses, and board size contributions may be reduced. Harmonic termination may be provided within the BAW resonator network or a prematch stage to improve efficiency of a power amplifier.

摘要： Embodiments of the present invention provide systems, devices and methods for improving both the bandwidth of a BAW resonator bandpass filter and the suppression of out-of-band frequencies above the passband. In various embodiments of the invention, blocker inductors are located in series between the filter input and the filter output to realize both bandwidth enhancement and improved out-of-band frequency rejection. For example, a first blocker inductor may be located at the input and a second blocker inductor may be located at the output of a BAW resonator bandpass filter.

摘要： A monostable circuit responsive conditionally to a circuit input signal for generating a circuit output signal having a pulse of a predetermined duration includes an AND gate having two input ports and an output port. ONe of the input ports is coupled to the circuit input signal and inverts that signal. The other of the input ports is coupled to the circuit output signal. A reset OR gate receives a reset signal and the output of the AND gate. When the reset signal is low, the reset OR gate outputs the output of the AND gate, thus enabling the curcuit. The output of the reset OR gate also goes to a ramp generator having a ramp capacitor, the charging current to which is provided by a current driver. The reference voltage for a comparator is provided by circuitry identical to that associated with the ramp capacitor except that an intermediate bias reference is applied to it. This bias reference is compensated for the effect temperature changes on the circuit. An external current source operating through a current mirror drives the capacitor current driver and the reference voltage. The outputs of the comparator and the reset OR gate are input into the output OR gate for producing the circuit output signal. When the output signal is low, or logic true, the AND gate is latched so that changes in the circuit input signal during this time period do not affect circuit operation.
