xrench 0.1.0

Utility functions.

🔧 xrench

Utility functions for pint and xarray to support RF and microwave design Python tools.

Installation

uv add xrench

Or with pip:

pip install xrench

Features

• Unit-aware arrays — Seamless integration between pint and xarray for physical quantities
• Custom RF units — Built-in support for dBK (decibel kelvin) and dBHz (decibel hertz)
• Unit decorator — wraps_xr decorator to strip and re-apply units around functions, preserving xarray coordinates and dimensions
• Rotation utilities — Apply scipy rotations to coordinate DataArrays, including polarization rotation
• Logging control — Mutable/unmutable logger via XRENCHLogger for clean library logging

Usage

Unit Registry

from xrench.units import ureg

# Use built-in RF units
noise_temp = 290 * ureg.decibelkelvin
bandwidth = 1e6 * ureg.decibelhertz

Convert kwargs to DataArrays

from xrench.xrutils import kw2da

arrays = kw2da(frequency=freq_quantity, angle=angle_array)

Unit-preserving function decorator

from xrench.xrutils import wraps_xr

@wraps_xr(ret_units="meter", arg_units=["meter", "meter"])
def my_func(x, y):
    # work with unit-less DataArrays
    return x + y

Logging

from xrench.logcontrol import XRENCHLogger

XRENCHLogger.unmute()         # enable logs
XRENCHLogger.level = "DEBUG"  # change level
XRENCHLogger.mute()           # silence logs
