Frequently Asked Questions
What frequency ranges does the wireless audio catalog cover?
The wireless audio portfolio covers the bands typically used for professional and consumer audio: UHF (470–698 MHz, professional wireless microphones), 900 MHz ISM (902–928 MHz US, 868 MHz EU), 1.9 GHz (DECT and licensed wireless mic), 2.4 GHz ISM (Bluetooth, proprietary digital wireless), and 5 GHz (newer professional and consumer digital audio links).
Are sub-GHz ISM-band parts available?
Yes. Low-current LNAs and broadband gain blocks cover the 433 MHz, 868 MHz (EU), and 902–928 MHz (US) ISM bands used by long-range, low-power wireless audio links and sensor networks. Most parts in this range are battery-friendly with single-supply operation.
What linearity characteristics matter for wireless audio?
Wireless audio links typically use narrow-band FM or low-bandwidth digital modulations (QPSK, 16-QAM) with low peak-to-average ratio, so OIP3 and OP1 requirements are modest compared to cellular or Wi-Fi. The dominant selection criteria are noise figure (sets transmission range), supply current (battery life for portable transmitters and receivers), and frequency coverage.
