MAX41461/MAX41462

300MHz–960MHz ASK Transmitter with I²C

Interface

General Description

Benefits and Features

The MAX41461/MAX41462 is a UHF sub-GHz ISM/SRD

transmitter is designed to transmit On-Off Keying (OOK)

or Amplitude-Shift Keying (ASK) data in the 286MHz to

960MHz frequency range. It integrates a fractional phase-

locked-loop (PLL), so 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 in-

creased range and security. The chip also features pre-

set modes with pin-selectable frequencies so that only

one wire is required for external microcontroller interface.

The only frequency-dependent components required are

for the external antenna matching network. Optionally,

the device can be put into programmable mode and

● Low Implementation Cost

• Bits-to-RF Single Wire Operation

• Low Bill-of-Materials (BOM)

• Uses Single, Low-Cost, 16MHz Crystal

• Small 3mm x 3mm µMAX-10 Package

● Increased Range, Data Rates, and Security

• Up to +16dBm PA Output Power

• Fast Frequency Switching for FHSS/DSSS

• Fast-On Oscillator: < 250μs Startup Time

• Up to 200kbps NRZ Data Rate

● Extend Battery Life with Low Supply Current

• Pin Selectable 300MHz–928MHz Frequencies

• Pin Compatible ASK and FSK Versions

• +1.8V to +3.6V Single-Supply Operation

• Fully Programmable with 400kHz/1MHz

nates many of the common problems with SAW-

based transmitters by providing greater modulation

depth, faster frequency settling, higher tolerance of the

transmit frequency, and reduced temperature depen-

dence. A clock-out signal at 800kHz is also provided.

I C Interface

The MAX41461/MAX41462 provides output power up to

+13dBm into a 50Ω load while drawing < 8mA (Manches-

ter coded). The output load can be adjusted to increase

power up to +16dBm, and a PA boost mode can be en-

abled at frequencies above 850MHz to compensate for

losses. The PA output power can also be controlled us-
