GENERAL DESCRIPTION

The ADL5363 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

ADL5363 incorporates an RF balun to provide optimal

performance over a 2300 MHz to 2900 MHz input frequency

range. 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 might otherwise result in the degradation of

dynamic performance.

Figure 1.

The ADL5363 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 ADL5363 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 (<200 μA) the circuit when desired.

The ADL5363 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.
