HHM1908A1

Balun Overview

The HHM1908A1 is a signal conditioning LTCC balun transformer manufactured by TDK Corporation. It operates within the 2400-2500 MHz frequency range, providing impedance transformation between balanced and unbalanced lines. The component features a 75 Ohm impedance specification and utilizes Surface Mount Device (SMD/SMT) termination for board mounting. It is housed in a compact 0402 (1005 metric) package. The device supports an operating temperature range from -40°C to +85°C. Key electrical performance includes an insertion loss of 0.8 dB. This component belongs to the HHM series and is classified under filters and signal conditioning products.
