6V, 1W RF Power Transistors for 900MHz Applications ____________________________Features ♦ Low Voltage: Operates from 1 Li-Ion or 3 NiCd/NiMH Batteries ♦ DC-to-Microwave Operating Range ♦ 1W Output Power at 900MHz ♦ On-Chip Diode for Accurate Biasing (MAX2602) ♦ Low-Cost Silicon Bipolar Technology ♦ Does Not Require Negative Bias or Supply Switch ♦ High Efficiency: 58% General Description The MAX2601/MAX2602 are RF power transistors optimized for use in portable cellular and wireless equipment that operates from three NiCd/NiMH cells or one Li-Ion cell.
These transistors deliver 1W of RF power from a 3.
6V supply with efficiency of 58% when biased for constant-envelope applications (e.
g.
, FM or FSK).
For NADC (IS-54) operation, they deliver 29dBm with -28dBc ACPR from a 4.
8V supply.
The MAX2601 is a high-performance silicon bipolar RF power transistor.
The MAX2602 includes a highperformance silicon bipolar RF power transistor, and a biasing diode that matches the thermal and process characteristics of the power transistor.
This diode is used to create a bias network that accurately controls the power transistor’s collector current as the temperature changes.
The MAX2601/MAX2602 can be used as the final stage in a discrete or module power amplifier.
Silicon bipolar technology eliminates the need for voltage inverters and sequencing circuitry, as required by GaAsFET power amplifiers.
Furthermore, a drain switch is not required to turn off the MAX2601/MAX2602.
This increases operating time in two ways: it allows lower system end-of-life battery voltage, and it eliminates the wasted power from a drain-switch device.
The MAX2601/MAX2602 are available in thermally enhanced, 8-pin SO packages, which are screened to the extended temperature range (-40°C to +85°C).
