1200 MHz TO 2500 MHz Balanced Mixer, LO Buffer and RF Balun

Manufactured by:

Product Details

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 high-side LO injection for RF frequencies from 1700 MHz to 2500 MHz and low-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 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.

The ADL5365 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 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.

Product Details

ADL5365-EVALZ is a fully populated, 4-layer, Rogers 3003-based evaluation board. It requires a 5 V/95 mA or 3.3 V/56 mA power supply for normal operation. The power supply should be connected to the clip leads labeled VPOS and GND. All signal ports are populated with edge-mounted SMA connectors. RF-IN is the input port for down-converting evaluation, and the output port for up-converting evaluation. LO1_IN and LO2_IN are input ports for local oscillators. LO1_IN is enabled when the LOSEL clip lead is logic low. LO2_IN is enabled when LOSEL is pulled to logic high. IF1-OUT is the output port for up-converting evaluation, and the input port for up-converting evaluation. Power down feature is available for power supply at or under 3.6 V.
