6 / 11 page HMC8038 Data Sheet Rev. A | Page 6 of 11 PIN CONFIGURATION AND FUNCTION DESCRIPTIONS 12 11 10 1 3 4 9 2 VDD VCTL RFC NC RF2 GND GND RF1 HMC8038 TOP VIEW (Not to Scale) NOTES 1. NC = NO CONNECT. THE PINS ARE NOT CONNECTED INTERNALLY; HOWEVER, ALL DATA SHOWN HEREIN WAS MEASURED WITH THESE PINS CONNECTED TO RF/DC GROUND EXTERNALLY. 2. EXPOSED PAD. EXPOSED PAD MUST BE CONNECTED TO RF/DC GROUND. Figure 3. Pin Configuration Table 5. Pin Function Descriptions Pin No. Mnemonic Description 1 VDD Supply Voltage Pin. 2 VCTL Control Input Pin. See Figure 5 for the VCTL interface schematic. Refer to Table 6 and the recommended input control voltage range in Table 2. 3 RFC RF Common Port. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required on this pin. 4, 6 to 8, 13 to 16 NC Not Internally Connected. These pins are not internally connected; however, all data shown in this data sheet is measured with the NC pins externally connected to RF/dc ground on the evaluation board. 5 EN Enable Input Pin. See Figure 5 for the EN interface schematic. Refer to Table 6 and the recommended input control voltage range in Table 2. 9 RF1 RF Port 1. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required on this pin. 10, 11 GND Ground. The package bottom has an exposed metal pad that must connect to the printed circuit board (PCB) RF ground. See Figure 4 for the GND interface schematic. 12 RF2 RF Port 2. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required on this pin. EPAD Exposed Pad. Exposed pad must be connected to RF/dc ground. INTERFACE SCHEMATICS GND Figure 4. GND Interface Schematic VDD VCTL, EN Figure 5. Logic Control Interface Schematic Table 6.
