                  The ADL5354 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
                  ADL5354 incorporates the RF baluns, allowing for optimal
                  performance over a 2300 MHz to 2900 MHz RF input frequency
                  range. 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.
                  The ADL5354 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 ADL5354 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 ADL5354 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 &#8722;40℃ to +85℃ temperature range.
