A shunt capacitor to ground matches the input for return loss and optimum NF. 4 BIAS1_VCC1 Bias Positive Power Supply for the LNA and Preamplifier. 5 H/L High or Low Gain Select, controls the LNA high and low gain modes. 6 PE2 This pin along with pin PE1 and bit M(0) of PLL_PE determine which of various operational modes will be active. Please refer to the Power Enable Truth Table. 7 PE1 This pin along with pin PE2 and bit M(0) of PLL_PE determine which of various operational modes will be active. Please refer to the Power Enable Truth Table. 8 TX_VCC1 Transmit Amplifier Positive Power Supply, requires a high quality decoupling capacitor and a short return path. 10 TXA_OUT Transmit Amplifier Output, internally matched to 50 Ω, requires an external DC blocking capacitor. 12 TX_VCC1 Transmit Amplifier Positive Power Supply. 13 TXA_IN Transmit Amplifier Input, internally AC coupled. 15 LE Synthesizer Latch Enable, the serial interface is active when LE is low and the serial data is latched into defined registers on the rising edge of LE. 16 DATA Synthesizer Serial Data Input, clocked in on the rising edge of the serial clock, MSB first. 17 CLK Synthesizer Clock, DATA is clocked in on the rising edge of the serial clock, MSB first. 18 REF_BY Synthesizer Reference Frequency Input Bypass, internally DC coupled and requires an external bypass to ground when REF_IN is used as a Single Ended input, requires an external AC coupling capacitor when used as a differential input.
