The ADL5365 uses a highly linear, doubly balanced passive mixer core along with integrated RF and LO balancing circuitry to allow for single-ended operation. The ADL5365 incorporates an RF balun, allowing for optimal performance over a 1200 MHz to 2500 MHz RF input frequency range using low-side LO injection for RF frequencies from 1700 MHz to 2500 MHz and high-side injection for frequencies from 1200 MHz to 1700 MHz. The balanced passive mixer arrangement provides good LO to RF leakage, typically better than −30 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 may otherwise result in the degradation of dynamic performance.The ADL5365 provides two switched LO paths that can be used in test driven development (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 ADL5365 is capable of operation at voltages down to 3.3 V with substantially reduced current. Under low voltage operation, an additional logic pin is provided to power down (<200 µA) the circuit when desired.The ADL5365 is fabricated using a BiCMOS high performance IC process. The device is available in a 5 mm × 5 mm, 20-lead LFCSP, and operates over a −40°C to +85°C temperature range. An evaluation board is also available.ApplicationsCellular base station receiversTransmit observation receiversRadio link downconverters

The ADL5380 is a broadband quadrature I-Q demodulator that covers an RF/IF input frequency range from 400 MHz to 6 GHz. With a NF = 10.9 dB, IP1dB = 11.6 dBm, and IIP3 = 29.7 dBm @ 900 MHz, the ADL5380 demodulator offers outstanding dynamic range suitable for the demanding infrastructure direct-conversion requirements. The differential RF inputs provide a well-behaved broadband input impedance of 50 Ω and are best driven from a 1:1 balun for optimum performance.Excellent demodulation accuracy is achieved with amplitude and phase balances of ~0.07 dB and ~0.2°, respectively. The demodulated in-phase (I) and quadrature (Q) differential outputs are fully buffered and provide a voltage conversion gain of ~7 dB. The buffered baseband outputs are capable of driving a 2 Vp-p differential signal into 200 Ω.The fully balanced design minimizes effects from second-order distortion. The leakage from the LO port to the RF port is <−50 dBm. Differential dc offsets at the I and Q outputs are typically <20 mV. Both of these factors contribute to the excellent IIP2 specification, which is >65 dBm.The ADL5380 operates off a single 4.75 V to 5.25 V supply. The supply current is adjustable by placing an external resistor from the ADJ pin to either the positive supply, VS, (to increase supply current and improve IIP3) or to ground (which decreases supply current at the expense of IIP3).The ADL5380 is fabricated using the Analog Devices, Inc., advanced silicon-germanium bipolar process and is available in a 24-lead exposed paddle LFCSP.APPLICATIONSCellular W-CDMA/GSM/LTEMicrowave point-to-(multi)point radiosBroadband wireless and WiMAX
