AD8361ARMZ from Analog Devices, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VPOS	power_in	Supply voltage pin with an operational range of 2.7 V to 5.5 V.
2	IREF	input	Output reference control pin; internal reference mode is enabled when it is left open, otherwise it must be tied to VPOS, and it must not be grounded.
3	RFIN	input	Signal input pin that must be driven from an ac-coupled source, with a low frequency real input impedance of 225 Ω.
4	PWDN	input	Power-down pin; a logic low below 100 mV enables detector operation, while a logic high above VS − 0.5 V turns the device off.
5	COMM	power_in	Device ground pin.
6	FLTR	passive	A capacitor between this pin and VPOS lowers the corner frequency of the modulation filter, whose on-chip filter is 27 pF
7	VRMS	output	Output pin with near rail-to-rail voltage and limited current drive, with an expected load greater than 10 kΩ to ground.
8	SREF	input	Supply reference control pin; it must be connected to VPOS to enable supply reference mode, otherwise it should be connected to COMM (ground).
