RF Module for Cordless Telephone in Japan Use
TRM7P/F-J Series
OUTLINE
The MITSUMI TRM7P/F-J series have been
developed by modifing the transmitting/receiving
circuit, audio modulator and demodulator circuit,
and PLL circuit of the Japanese market-oriented
small power cordless telephones into compact
and light weight modules.
Telecommunication component
FEATURES
1. For small power cordless telephones in the Japanese market. (Frequency bands used 250MHz and 380MHz.)
2. Achieves 8cc capacity.
3. Ultra-small, Ultra-thin (39 28 8 : Except Connector Part).
4. Light weight, at 13g
5. Two types of mounting configurations are available : the board mounting type (TRM7P) and FPC connector
type (TRM7F).
6. Low current consumption and low voltage operation. (Built-in 2V regulator) Also, the design supports
uniaxial and bi-axial antennas.
