LM-400Page Number : 4 of 6Note :Measurement made using a POWER_TABLE entery of TX_PRE 80, INT PA63, EXT PA255. This ensures that theBluetooth requirements for ACP and those defined by the FCC and ETSI are satisfied over the operatingtemp erature rang of -5Ð to + 45Ð . Although the design is capable of generating in excess of + 18dBm,regulatory compliance over the full temperature range of -5Ð to + 45Ð will not be satisfied if the transmit powerapproaches this value.0121 270 6232 | www.lm-technologies.com | sales@lm-technologies.com Maximum carrier frequency stability | w0 + wi | RMS DVEM - 7- < 20 % 99% DEVM - 13- < 30 % π/4 DQPSK Modulation Accuracy Peak DEVM - 19- < 35 % RMS DVEM - 7- < 13 % 99% DEVM - 13- < 20 % 8 DPSK Modulation Accuracy Peak DEVM - 17- < 25 % F>F0+3 MHz - <-50 - < -40 dBm F<F0-3 MHz - <-50 - < -40 dBm F=F0-3 MHz - -46 - < -40 dBm F=F0-2 MHz - -34 - < -20 dBm F=F0-1 MHz - -35 - < -26 dBm F=F0+1 MHz - -35 - < -26 dBm F=F0+2 MHz - -31 - < -20 dBm In-band spurious emissions F=F0+3 MHz - -33 - < -40 dBm EDR Differential Phase Encoding No Errors > 99 % Receiver , VDD = 3.3V Temperature =+20°C htooteulB .xaM .pyT.niM noitaludoM Specification Unit π/4 DQPSK - -87 - < -70 dBm Sensitivity at 0.1% BER 8 DPSK - -78 - < -70 dBm π/4 DQPSK - -8 - > -20 dBm Maximum received signal level at 0.1% BER 8 DPSK - -10 - > -20 dBm π/4 DQPSK - 10 - < +13 dB C/I co-channel at 0.1% BER 8 DPSK - 19 - < +21 dB π/4 DQPSK - -10 - < 0 dB Adjacent channel selectivity C/I F=F0+1 MHz 8 DPSK - -5 - < +5dB π/4 DQPSK - -11 - < 0 dB Adjacent channel selectivity C/I F=F0-1 MHz 8 DPSK - -5 - < +5dB π/4 DQPSK - -40 - < -30 dB Adjacent channel selectivity C/I F=F0+2 MHz 8 DPSK - -40 - < -25 dB π/4 DQPSK - -23 - < -20 dB Adjacent channel selectivity C/I F=F0-2 MHz 8 DPSK - -20 - < -13 dB π/4 DQPSK - -45 - < -40 dB Adjacent channel selectivity C/I F=F0+3 MHz 8 DPSK - -45 - < -33 dB π/4 DQPSK - -45 - < -40 dB Adjacent channel selectivity C/I F=F0-5 MHz 8 DPSK - -45 - < -33 dB F0= 2405, 2441, 2477 MHz π/4 DQPSK -20 < -7 dB Adjacent channel selectivity C/I F=Fimage8 DPSK -15 < 0 dB
