The Lepida S4L054 from Antenova mounts on a PCB like any other SMT component.
Devices that connect to 5G and LTE networks need antennas. U.K.-based Antenova’s Lepida S4L054 is an SMT device that mounts directly on your PCB.
It covers the FR1 frequencies used for cellular communications by supporting the following cellular frequency bands:
- 617 MHz to 698 MHz
- 698 MHz to 798 MHz
- 824 MHz to 960 MHz
- 1710 MHz to 2170 MHz
- 2300 MHz to 2400 MHz
- 2500 MHz to 2690 MHz
- 3300 MHz to 3800 MHz
The S4L054 antenna has a 50 Ω impedance and requires a matching circuit to properly tune it to your application. The circuit may consist of up to six passive components — resistors, inductors, and capacitors — five of which connect between your power amplifier and the antenna’s feed pin, with possibly one resistor to RF ground. The datasheet provides component values for use with a reference board.
