4 / 31 page www.ti.com RF OUTPUT PERFORMANCE (942.5 MHz) TRF3701 SLWS145D – FEBRUARY 2003 – REVISED AUGUST 2006 Over recommended operating conditions, VCC = 5 V, VCM = 3.7 V, f LO = 942.5 MHz at 0 dBm, TA = 25°C (unless otherwise noted)(1) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Single and Two-Tone Specifications Output power –3.5 –1 dBm Second baseband –50 –45 dBc harmonic (USB or LSB)(3) I, Q(2) = 1 Vp-p, fBB = 928 kHz Third baseband harmonic –61 –55 dBc (USB or LSB)(3) I, Q(2) = 1 Vp-p (two-tone signal, fBB1 = 928 kHz, IMD3 –55 –45 dBc fBB2 = 992 kHz) P1dB (output compression 6.5 dBm point) I, Q(4) = VCM = 3.7 VDC –156 6-MHz offset from carrier, Pout = –10 dBm, over temperature –153 –151(5) NSD Noise spectral density dBm/Hz 6-MHz offset from carrier, Pout = –5 dBm, over temperature –152 –150(5) 6-MHz offset from carrier, Pout = 0 dBm, over temperature –150 –148(5) RFOUT pin impedance 26 + j3 Ω I, Q(2) = 1 Vp-p, fBB = 928 kHz, unadjusted 30 35 Carrier suppression I, Q(2) = 1 Vp-p, fBB = 928 kHz, optimized 55 dBc I, Q(2) = 1 Vp-p, fBB = 928 kHz, over temperature 35 I, Q(2) = 1 Vp-p, fBB = 928 kHz, unadjusted 37 50 Sideband suppression I, Q(2) = 1 Vp-p, fBB = 928 kHz, optimized 55 dBc I, Q(2) = 1 Vp-p, fBB = 928 kHz, over temperature 38 (1) Baseband inputs are differential; equivalent performance is attained by using single-ended drive. (2) I , Q = 1 Vp-p implies that the magnitude of the signal at each input pin IVIN, IREF, QVIN, QREF is equal to 500 mVp-p. (3) USB = upper sideband. LSB = lower sideband. (4) All input pins tied to VCM (5) Maximum noise values are assured by statistical characterization only, not production testing. The values specified are over the entire temperature range, TA = –40°C to 85°C. 4 Submit Documentation Feedback |
