The ADL5385 is a silicon, monolithic, quadrature modulator designed for use from 50 MHz to 2200 MHz. Its excellent phase accuracy and amplitude balance enable both high performance analog modulation applications.
The ADL5385 is a monolithic quadrature modulator designed for radio‑link infrastructure, cable‑modem termination, and broadband wireless access systems. It accepts differential baseband inputs and up‑converts them to two carriers in quadrature using an external local‑oscillator input at twice the desired output frequency.
Key specifications include an output frequency range of 50 MHz to 2200 MHz, single‑supply operation from 4.75 V to 5.5 V, and performance parameters such as sideband suppression up to –50 dBc and carrier feedthrough around –46 dBm. The device is packaged in a 24‑lead Pb‑free LFCSP_VQ with exposed paddle and operates from –40 °C to +85 °C.
