Figure 1. GENERAL DESCRIPTION The ADL5369 uses a highly linear, doubly balanced passive mixer The ADL5369 provides two switched LO paths that can be core along with integrated radio frequency (RF) and local oscillator used in time division duplex (TDD) applications where it is (LO) balancing circuitry to allow single-ended operation. The desirable to rapidly switch between two local oscillators. LO ADL5369 incorporates an RF balun, allowing optimal performance current can be externally set using a resistor to minimize dc over a 300 MHz to 1100 MHz RF input frequency range. The current commensurate with the desired level of performance. balanced passive mixer arrangement provides good LO to RF For low voltage applications, the ADL5369 is capable of operation leakage, typically better than 25 dBm, and excellent intermod- at voltages down to 3.3 V with substantially reduced current. ulation performance. The balanced mixer core also provides Under low voltage operation, an additional logic pin is provided extremely high input linearity, allowing the device to be used in to power down (<200 A) the circuit when desired. demanding cellular applications where in-band blocking signals The ADL5369 is fabricated using a BiCMOS high performance may otherwise result in the degradation of dynamic perform- IC process. The device is available in a 5 mm 5 mm, 20-lead ance. The passive mixer core yields a typical power conversion loss LFCSP and operates over a 40C to +85C temperature range. of 6.2 dB. An evaluation board is also available. Table 1.
