Data Sheet ADL5375 Rev. C | Page 31 of 36 Table 9. Evaluation Board Description and Configuration Options Component Description Default Condition/Option Settings VPOS, GND Test Points Power supply and ground test points for clip leads Red = 5 V, black = GND S1 Switch, R6, R15 DSOP output disable select Position A = output enabled Position B = output disabled R15 = 49.9 Ω (0603) R6 = 10 kΩ (0603) R7, R12 AC limiting resistors R7, R12 = 100 Ω (0603) C16 to C18, R14, R16, R18, R19 LO input filter components R14 , R18 = 0 Ω (0603) R16, R19, C16 to C18 = open (0603) C6, C7 LO driving capacitor C6, C7 = 100 pF (0402) LOIP SMA, R17, R20, R21, R22, T1, T2, T2A Single-ended local oscillator input R17 = 0 Ω (0603) R20 = open (0402) R21 = 0 Ω (0402) R22 = open (0603) T1, T2, T2A = open LOIN SMA, R16, R17, R19, R20, Optional differential LO input at LOIN R16, R19 = 0 Ω (0603) R21, R22, T1, T2, T2A R20, R21 = 0 Ω (0402) R17, R22 = open (0603) T1, T2, T2A = open LOIP SMA, T1 (or T2, T2A), R17, R20, R21, R22 Optional differential LO driving with Balun at LOIP R17 = open (0603) R20, R21 = open (0402) R22 = 0 Ω (0603) T1 = TC1-1-43A+ or T2 = 3600BL14M050 or T2A = 5400BL15B050 C100, C101 Frequency tuning capacitors for RF driver amplifier Tuning for 1805 MHz to 2170 MHz Refer to the ADL5320 datasheet for the exact position according to the frequency C100 = 0.5 pF (0402) C101 = 1.5 pF (0402) C1 AC-coupling capacitor connects ADL5375 RF output to MOD_OUT RF connector or to ADL5320 RF input C1 = 100 pF (0402) R1 Resistor connects ADL5375 RF output to MOD_OUT (AMP_IN) SMA To check ADL5375 performance itself, a 0 Ω should be inserted at R1 and open R2. R1 = open (0402) To check ADL5320 performance itself, a 0 Ω should be inserted at R1 and R2 R2 Resistor connects ADL5375 RF output to ADL5320 RF input R2 = 0 Ω (0402) U1 ADL5375 quadrature modulator ADL5375-05 or ADL5375-15 U2 SOT-89 RF driver amplifier ADL5320 L1 DC bias Inductor L1 = 15 nH(0603) C2, C3, C4, C5, C9, C10, C11 Power supply bypassing capacitors C2, C3 = 100 pF (0402) C4, C5 = 0.1 µF (0402) C9 = 10 µF (1206) C10 = 10 nF (0603) C11 = 22 pF (0603) R13 Resistor to share power supply between the ADL5375 and the ADL5320. To turn on the ADL5320, a 0 Ω resistor should be installed in this location. R13 = 0 Ω (0603) |
