The ADL5375 is a broadband quadrature modulator designed for operation in the frequency range of 400 MHz to 6 GHz. It features 1 dB output compression, output return loss, noise floor, sideband suppression, and other characteristics. This product is suitable for cellular communication systems, broadband wireless access systems, satellite modems, and more.
The ADL5375 broadband quadrature modulator from Analog Devices operates from 400 MHz to 6 GHz and supports two differential baseband inputs with selectable bias levels (500 mV or 1500 mV). It is supplied in a 24‑lead LFCSP_VQ package and is intended for cellular, Wi‑MAX/LTE, satellite and other broadband RF applications.
Key features include a typical output power of up to 10 dBm, output return loss better than –12 dB, carrier feedthrough below –40 dBm, and sideband suppression better than –50 dBc. The device operates from a single 4.75 V‑5.25 V supply and meets a –40 °C to +85 °C temperature range.
| Output P1dB | 9.6 dBm – 10.5 dBm (depending on LO) |
|---|---|
| Output Return Loss | -16.4 dB to -20.7 dB |
| Carrier Feedthrough | < -40 dBm |
| Sideband Suppression | < -50 dBc |
| Quadrature Error | 0.01° – 1.7° |
| I/Q Amplitude Balance | 0.07 dB – 0.10 dB |
| Noise Floor | -160 dBm/Hz (typical) |
The device uses a single supply voltage of 4.75 V to 5.25 V.
ADL5375‑05 uses a 500 mV bias, while ADL5375‑15 uses a 1500 mV bias.
Yes, the ADL5375 is an ESD‑sensitive device and requires proper handling per JESD‑51‑2.
