HMC349AMS8GETR from Analog Devices, in a MSOP-8-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Positive supply voltage input, 3 V to 5 V (absolute max +7 V). Typical supply current 1.2 mA (3.5 mA max). Bypass capacitors are recommended on this pin to minimize RF coupling. |
| 2 | CTRL | input | Logic control input selecting which RF throw port is connected to RFC when EN is low. CMOS/TTL compatible: VINL = 0 to 0.8 V, VINH = 2 V to VDD. See truth table (Table 4): with EN low, CTRL=high selects RF1↔RFC, CTRL=low selects RF2↔RFC. |
| 3 | RFC | bidirectional | RF common port, dc-coupled and internally matched to 50 Ω over 0.1 GHz to 4 GHz. An external dc blocking capacitor is required. Path is bidirectional; can be used as RF input or output. |
| 4 | EN | input | Logic enable input. CMOS/TTL compatible (VINL ≤ 0.8 V, VINH ≥ 2 V). When EN=low the switch selects RF1 or RF2 per CTRL; when EN=high both RF paths are in isolation (all-off state) and RFC becomes open reflective. |
| 5 | RF1 | bidirectional | RF throw port 1, dc-coupled and internally matched to 50 Ω. Requires an external dc blocking capacitor. Handles up to 33.5 dBm through-path RF input power (VDD = 5 V, TCASE = 85°C). |
| 6 | GND | power_in | Ground. Must be connected to the RF/dc ground plane of the PCB. |
| 7 | GND | power_in | Ground. Must be connected to the RF/dc ground plane of the PCB. |
| 8 | RF2 | bidirectional | RF throw port 2, dc-coupled and internally matched to 50 Ω. Requires an external dc blocking capacitor. Handles up to 33.5 dBm through-path RF input power (VDD = 5 V, TCASE = 85°C). |
| EPAD | EPAD | power_in | Exposed thermal/RF pad on the package underside. Must be connected to the RF/dc ground plane of the PCB for proper electrical and thermal performance. |
