AC ELECTRICAL CHARACTERISTICS
(MAX2247 EV kit, V
Note 1: This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device
Note 2: Characteristics are production tested at T
Note 3: Idle current is controlled by external DAC for best efficiency over the entire output power range.
Note 4: Parameter is measured with RF modulation based on IEEE 802.11b standard.
Note 5: Minimum and maximum specifications are guaranteed by design and characterization.
Note 6: Operation outside this range is possible but not guaranteed.
Note 7: The total turn-on time required for PA output power to settle to within 0.5dB of the final value.
Note 8: Specification is corrected for PC board loss of approximately 0.3dB, on the output of the MAX2247 EV kit.
Note 9: Total turn-off time required for PA supply current to fall below 10µA.
Note 10: See the Typical Operating Characteristics for statistical variation.

can be exposed to during board-level solder attach and rework. This limit permits the use of only the solder profiles recom-
mended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and convection reflow.
Preheating is required. Hand or wave soldering is not recommended.
