The ADL5353 uses a highly linear, doubly balanced passive mixer core along with integrated RF and local oscillator (LO) balancing circuitry to allow for single-ended operation. The ADL5353 incorporates an RF balun to provide optimal performance over a 2200 MHz to 2700 MHz input frequency range using high-side LO. The balanced passive mixer arrangement provides good LO-to-RF leakage, typically better than −36 dBm, and excellent intermodulation 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 might 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 8.8 dB and can be used with a wide range of output impedances. The ADL5353 provides two switched LO paths that can be used in TDD applications where it is desirable to rapidly switch between two local oscillators. LO current can be externally set using a resistor to minimize dc current commensurate with the desired level of performance. For low voltage applications, the ADL5353 is capable of operation at voltages down to 3.3 V with substantially reduced current. For low voltage operation, an additional logic pin is provided to power down (20 dB over a limited bandwidth Typ Unit 2700 dB Ω MHz 450 5.5 Ω||pF MHz V 18 50 2200 Differential impedance, f = 200 MHz Externally generated Max 230||1.5 30 3.3 −6 5.0 0 15 50 2230 +10 3150 1.0 0.4 1.4 Device enabled, IF output to 90% of its final level Device disabled, supply current
