3 / 10 page dBm 2.5GHz, +20dBm Power Amplifier IC in UCSP Package _______________________________________________________________________________________ 3 AC ELECTRICAL CHARACTERISTICS (MAX2240 EV kit, VCC = +2.7V to +5V, PRFIN = 0dBm to +4dBm, fRFIN = 2.4GHz to 2.5GHz, SHDN = VCC, TA = +25°C. Typical values measured at VCC = +3.2V, PRFIN = +3dBm, fRFIN = 2.45GHz, unless otherwise noted.) All power levels set by D0, D1; any load phase angle, any duration All power levels set by D0, D1; load VSWR ≤ 3:1 SHDN = 1 to 0, D0 = D1 = logic high-to-low transition CONDITIONS 6:1 Maximum Output VSWR Without Damage (Note 8) dB 45 Input to Output Isolation in Shutdown dBm -30 Nonharmonic Spurious Output (Note 9) µs 2 Power Ramp Turn-Off Time (Notes 7, 9) UNITS MIN TYP MAX PARAMETERS VCC = 5.0V 26 8 Power Control Steps (Notes 4, 9) SHDN = 0 to 1, D0 = D1 = logic low-to-high transition µs 2 Power Ramp Turn-On Time (Notes 6, 9) dBm -15 -5 Harmonic Output (Notes 3, 9) RS = 50 Ω, over full Pin range dBm 1.5:1 2:1 In-Band Spurious Noise (Notes 5, 9) Frequency offset = ±550kHz dBc -21 -20 Frequency offset = ±1.5MHz dBm -20 Frequency offset = ±2.5MHz -40 Input VSWR (Note 9) VCC = 2.7V to 5.0V dB 2 8.6 Note 1: Limits are 100% production tested at TA = +25°C. Limits over the entire operating temperature range are guaranteed by design and characterization but are not production tested. Note 2: Supply current is measured with RF power applied to the input. Note 3: Measured with an output-matching network to minimize the 2nd and 3rd harmonics (see Applications section). Note 4: Power steps between adjacent power levels. All other operating conditions remain constant during power step change. Note 5: Output measured in 100kHz RBW. Test signal modulation shall comply with GFSK, BT = 0.5, 1-bit/symbol, 1Mbps, frequency deviation = 175kHz. Note 6: The total turn-on time for the PA output power to settle within 1dB of the final value. Note 7: The total turn-off time for the PA output power to drop to -10dBm. Note 8: After removal of the load mismatch, the PA returns to operation under normal conditions. Note 9: Guaranteed by design and characterization.
