The MAX41460 is a UHF sub-GHz ISM/SRD transmitter is designed to transmit On-Off Keying (OOK), Amplitude-Shift Keying (ASK), Frequency-Shift Keying (FSK), and Gaussian (G)FSK (or 2GFSK) data in the 286MHz to 960MHz frequency range. It integrates a fractional phase-locked-loop (PLL) so that a single, low-cost crystal can be used to generate commonly used world-wide sub-GHz frequencies. The fast response time of the PLL allows for frequency-hopping, spread spectrum protocols for increased range and security. The only frequency-dependent components required are for the external antenna-matching network.
The crystal-based architecture of the MAX41460 provides greater modulation depth, faster frequency settling, higher tolerance of the transmit frequency, and reduced temperature dependence.
The MAX41460 provides output power up to +13dBm into a 50Ω load while only drawing < 8mA for ASK (Manchester coded) and < 12mA for (G)FSK transmission at 315MHz. The output load can be adjusted to increase power up to +16dBm, and a PA boost mode can be enabled at frequencies above 850MHz to compensate for losses. The PA output power can also be controlled using programmable register settings.
The MAX41460 features single-supply operation from +1.8V to +3.6V. The device has an auto-shutdown feature to extend battery life and a fast oscillator wake-up on data activity detection. A serial programmable interface make the MAX41460 compatible with almost any microcontroller or code-hopping generator.
The MAX41460 is available in a 10-pin µMAX package and is specified over the -40°C to +105°C extended temperature range. The MAX41460 has an ESD rating of 2.5kV HBM.
