资 源 简 介
The ADL5357 uses a highly linear, doubly balanced passive mixer core along with integrated RF and LO balancing circuitry to allow for single-ended operaTIon. The ADL5357 incorporates an RF balun, allowing for opTImal performance over a 500 MHz to 1700 MHz RF input frequency range using high-side LO injecTIon for RF frequencies from 500 MHz to 1200 MHz and low-side injecTIon for frequencies from 900 MHz to 1700 MHz. The balanced passive mixer arrangement provides good LO-to-RF leakage, typically better than −46 dBm, and excellent inter-modulation performance. The balanced mixer core also provides extremely high input linearity, allowing the device to be used in demanding cellular applications where in-band blocking signals may otherwise result in the degradation of dynamic performance. A high linearity IF buffer amplifier follows the passive mixer core to yield a typical power conversion gain of 8.6 dB and can be used with a wide range of output impedances.
