Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADRF5545 is a dual-channel configuration consisting of a cascaded two-stage low-noise amplifier (LNA) and a high-powered silicon single-drop double-throw (SPDT) switch.

In high gain mode, the cascaded two stage LNA and switch provide a low noise figure (NF) of 1.45 dB and a high gain of 32 dB at 3.6 GHz and an output 3rd order intermodulation point (OIP3) of 32 dBm (typical). In low gain mode, one of the two LNA stages is bypassed, providing 16 dB of gain at a lower current of 36 mA. In off mode, the LNA is switched off and the device current consumption is 12 mA.

During transmit, the switch provides a low insertion loss of 0.65 dB when the RF input is connected to the end electrode pin (TERM-ChA or TERM-ChB) and handles 40 dBm of Long Term Evolution (LTE) average power (9 dB peak/average ratio (PAR)) over its lifetime, compared to 43 dBm in single event (<10 seconds) LNA protection mode. dBm.

The device is available in a compact RoHS compliant 6 mm × 6 mm 40-pin LFCSP package.
