The AD8341 is an RF vector modulator with a frequency range of 1.5 GHz to 2.4 GHz. It features Cartesian amplitude and phase modulation, continuous magnitude and phase control, output third-order intercept and 1 dB compression point, adjustable modulation bandwidth, etc.
The AD8341 vector modulator provides arbitrary amplitude and phase modulation of an RF signal over a 1.5 GHz to 2.4 GHz frequency range. It supports continuous magnitude control from –4.5 dB to –34.5 dB and continuous phase control from 0° to 360°, making it suitable for RF PA linearization, smart antennas, and variable attenuator/phase‑shifter applications.
The device operates from a single 4.75 V to 5.25 V supply, draws about 125 mA, and is packaged in a 24‑lead lead‑frame chip‑scale (LFCSP) package. Key performance figures include an output 1 dB compression point of 8.5 dBm, OIP3 of 17.5 dBm, and an output noise floor of –150.5 dBm/Hz. It is rated for –40 °C to +85 °C operation.
