Electrical characteristics are measured with all RF ports terminated in 50Ω.
∗ Harmonics measured with Tx inputs harmonically matched. The use of harmonic matching is recommended
to ensure optimum performance.
∗1 Power incident on GSM Tx, Pin = 34dBm, 880 to 915MHz, VDD = 5.0V, GSM Tx enabled
∗2 Power incident on DCS Tx, Pin = 32dBm, 1710 to 1785MHz, VDD = 5.0V, DCS Tx enabled
∗3 Power incident on ANT, Pin = 10dBm, 925 to 960MHz, VDD = 5.0V, GSM Rx enabled
∗4 Power incident on ANT, Pin = 10dBm, 1805 to 1880MHz, VDD = 5.0V, DCS Rx enabled
