ADL5369

13361-001 Data Sheet 300 MHz to 1100 MHz Balanced Mixer, LO Buffer, and RF Balun ADL5369 FEATURES RF frequency range of 300 MHz to 1100 MHz IF frequency range of 30 MHz to 450 MHz Power conversion loss: 6.2 dB SSB noise figure of 7.2 dB Input IP3 of 28 dBm Typical LO interface return loss of 0 dBm Single-ended, 50 Ω RF and LO input ports High isolation SPDT LO input switch Typical single-supply operation: 3.3 V to 5 V Exposed pad, 5 mm × 5 mm, 20-lead LFCSP APPLICATIONS Cellular base station receivers Transmit observation receivers Radio link downconverters GENERAL DESCRIPTION The ADL5369 uses a highly linear, doubly balanced passive mixer core along with integrated radio frequency (RF) and local oscillator (LO) balancing circuitry to allow single-ended operation. The ADL5369 incorporates an RF balun, allowing optimal performance over a 300 MHz to 1100 MHz RF input frequency range. The balanced passive mixer arrangement provides good LO to RF leakage, typically better than −25 d...
