General Description

The MAX7058 UHF transmitter alternately transmits

ASK/OOK data at 315MHz or 390MHz using a single

crystal. The MAX7058 has internal tuning capacitors at

the output of the power amplifier that can be pro-

grammed for matching to the antenna or load. The

MAX7058 can transmit at a data rate up to 100kbps

NRZ (50kbps Manchester coded). Typical transmitted

power into a 50Ω load is +10dBm. The MAX7058 oper-

ates from +2.1V to +3.6V and draws under 8.0mA of

current. The standby current is less than 1µA at room

temperature. A 15MHz crystal is used as the reference

for 315MHz and 390MHz operation by selecting synthe-

sizer-divide ratios of 21 and 26, respectively.

The MAX7058 is available in a 4mm x 4mm, 24-pin thin

QFN package and is specified to operate in the -40°C

to +125°C automotive temperature range.
