The primary RF microstrip line is 50 Ω. 2. Components shown on the silkscreen but not on the schematic are not used. 3. The center of L3 is placed at 0.095” (8.1 ° @ 1960 MHz) from the center C2. 4. The center of C2 is placed at 0.135” (11.5 ° @ 1960 MHz) from the edge of the AP602 (U1). 5. The center of C30 is placed at 0.580” (49.6 ° @ 1960 MHz) from the edge of the AP602 (U1). 6. The bold-faced RF trace is for the DC bias feed. The stub’s length is approximately a ¼ λ. 7. The main RF trace is cut at component location L3 for this particular reference design. 1930-1990 MHz Application Circuit Performance Plots W-CDMA 3GPP Test Model 1+64 DPCH, 60% clipping, PAR = 8.6 dB @ 0.01% Probability, 3.84 MHz BW Gain vs. Output Power vs. Frequency CW tone, Vcc = 28V, Icq = 80 mA, 25 ˚C 11 12 13 14 15 16 26 28 30 32 34 36 Output Power (dBm) 1930 MHz 1960 MHz 1990 MHz S11, S22 vs. Frequency Vcc = 28V, Icq = 80 mA, 25 ˚C -25 -20 -15 -10 -5 0 1.8 1.85 1.9 1.95 2 2.05 2.1 Frequency (GHz) S11 S22 Efficiency vs. Output Power vs. Frequency CW tone, Vcc = 28V, Icq = 80 mA, 25 ˚C 0 10 20 30 40 50 60 16 20 24 28 32 36 Output Power (dBm) 1930 MHz 1960 MHz 1990 MHz ACLR1 vs. Output Power vs. Frequency WCDMA, Vcc = 28V, Icq = 80 mA, 25 ˚C -65 -60 -55 -50 -45 -40 18 20 22 24 26 28 Average Output Power (dBm) 1930 MHz 1960 MHz 1990 MHz IMD vs. Output Power CW 2-tone signal, 1960 MHz, ∆f = 1 MHz, 28V, 80 mA Icq, 25 ˚C -80 -70 -60 -50 -40 22 24 26 28 30 32 Output Power, PEP (dBm) IMD3L IMD3U IMD5 Efficiency vs. Output Power vs. Frequency WCDMA, Vcc = 28V, Icq = 80 mA, 25 ˚C 0 5 10 15 20 25 18 20 22 24 26 28 Average Output Power (dBm) 1930 MHz 1960 MHz 1990 MHz C30 2.4pF See note 5 C2 2.7pF See note 4 4.7 nH See note 3 L3 C7 1000pF W = .030” L = .980” C27 10pF C30 |
