GENERAL DESCRIPTION

The ADL5356 uses a highly linear, doubly balanced, passive mixer

core along with integrated RF and local oscillator (LO) balancing

circuitry to allow single-ended operation. The ADL5356

incorporates the RF baluns, allowing for optimal performance over

a 1200 MHz to 2500 MHz RF input frequency range. Performance

is optimized for RF frequencies from 1700 MHz to 2500 MHz

using a low-side LO and RF frequencies from 1200 MHz to

1700 MHz using a high-side LO. The balanced passive mixer

arrangement provides good LO-to-RF leakage, typically better

than −35 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. A high linearity IF buffer

amplifier follows the passive mixer core to yield a typical power

conversion gain of 8.2 dB and can be used with a wide range of

output impedances.

Figure 1.

The ADL5356 provides two switched LO paths that can be used

in TDD applications where it is desirable to ping-pong 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 ADL5356 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 (<300 µA) the circuit when desired.

The ADL5356 is fabricated using a BiCMOS high performance

IC process. The device is available in a 6 mm × 6 mm, 36-lead

LFCSP and operates over a −40°C to +85°C temperature range.

An evaluation board is also available.
