| Preliminary Technical Data FEATURES RF Frequency 700MHz to 1000MHz IF Frequency 50MHZ to 350MHz Power Conversion Gain of 8.5dB SSB Noise Figure of 9.5dB SSB NF with +10dBm blocker of 16.5dB Input IP3 of 26dBm Input P1dB of 10 dBm Typical LO Drive of 0 dBm Single-ended, 50 RF and LO Input Ports High Isolation SPDT LO Input Switch Single Supply Operation: 3.3 to 5 V Exposed Paddle 6 x 6 mm, 36 Lead LFCSP Package Dual 900MHz Balanced Mixer with Low Side LO Buffer, IF Amp, and RF Balun ADL5360 APPLICATIONS Cellular Base Station Receivers Main and Diversity Receiver Designs Radio Link Downconverters GENERAL DESCRIPTION The ADL5360 utilizes two highly linear doubly balanced passive mixer cores along with integrated RF and LO balancing circuitry to enable single-ended operation. The ADL5360 incorporates two RF baluns allowing for optimal main and diversity mixer performance over a 700 to 1000 MHz RF input frequency range using low-side LO injection. The balanced passive mixer arrangement provides good LO to RF leakage, typically better than -25dBm, and excellent intermodulation performance. The balanced mixer cores also provide 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. High linearity IF buffer amps follow the passive mixer cores, to yield a typical power conversion gain of 9.5dB. (For a higher IIP3 version of the dual mixer without the IF amplifiers, please contact the factory). The ADL5360 provides two switched LO paths that can be utilized in TDD applications where it is desirable to rapidly alternate between two local oscillators. LO current can be externally set using a resistor to minimize DC current REV. PrA Information furnished by Analog Devices is believed to be accurate and reliable.

An additional 3V logic pin is provided to power down (<100uA) the circuit when desired. For low voltage applications, the ADL5360 is capable of operation at voltages down to 3V with substantially reduced DC current. The ADL5360 is fabricated using a BiCMOS high performance IC process. The device is available in a 6mm x 6mm 36-lead LFCSP package and operates over a -40C to +85C temperature range. An evaluation board is also available. One Technology Way, P.O.

Eval Board Configuration Components C1, C4, C5, C8, C10, C12, C13, C15, C18, C21, C22, C23, C24, C25, C26 Function Power Supply Decoupling. Nominal supply decoupling consists a 0.01 F capacitor to ground in parallel with 10pF capacitors to ground positioned as close to the device as possible. Preliminary Technical Data Z1-Z4, C2, C3, C6, C7, C9, C22 T1, T2, C17, C19, C20, C27, C28, C29, C30, C31, C32, C33, L1, L2, L4, L5, R3, R6, R9, R10 C14, C16, R15, LOSEL R19, PWDN R1, R2, R4, R5,L3, L6, R7, R8, R11, R12, R13, R14, R16, R17, C34 RF Main and Diversity Input Interface. Main and Diversity input channels are ac-coupled through C9 and C22. Z1-Z4 provides additional component placement for external matching/filter networks. C2, C3, C6, and C7 provide bypassing for the center taps of the main and diversity on-chip input baluns. IF Main and Diversity Output Interface. The open collector IF output interfaces are biased through pull-up choke inductors L1, L2, L4, and L5, with R3 and R6 available for additional supply bypassing. T1 and T2 are 4:1 impedance transformers used to provide a single ended IF output interface, with C27 and C28 providing center-tap bypassing. C17, C19, C20, C29, C30, C31, C32, and C33 ensure an ac-coupled output interface. R9 and R10 should be removed for balanced output operation. LO Interface. C14 and C16 provide ac-coupling for the LOI1 and LOI2 local oscillator inputs. LOSEL selects the appropriate LO input for both mixer cores. R15 provides a pull-down to ensure LOI2 is enabled when the LOSEL jumper is removed. Jumper can be removed to allow LOSEL interface to be excercised using external logic generator. PWDN Interface. When the PWDN 2-pin shunt is inserted the ADL5356 is powered down. When open R19 pulls the PWDN logic low and enables the device. Jumper can be removed to allow PWDN interface to be excercised using external logic generator. It is permissible to ground the pwrdn pin for nominal operation. Bias Control. R16 and R17 form a voltage divider to provide a 3V for logic control, bypassed to ground through C34. R7, R8, R11, R12, R13, and R14 provide resistor programmability of VGS0, VGS1 and VGS2. Typically these nodes can be hard-wired for nominal operation. It is permissible to ground these pins for nominal operation. R2 and R5 set the bias point for the internal LO buffers. R1 and R4 set the bias point for the internal IF amplifiers. L3 and L6 are external inductors used to improve isolation and common mode rejection.
