PSPL5350 6 dB Power Divider, 50 GHz

기준 가격 범위


추가 정보:


The PSPL5350 6 dB Power Divider provides excellent amplitude and phase performance power division from DC to frequencies over 40 GHz. The outputs are nominally attenuated by 6 dB. All ports are impedance matched to 50 Ω when both outputs are terminated in 50 Ω. Power dividers are built using a three-resistor network. The resistors have 1% tolerances, resulting in precise 50 Ω impedance matches at any port. This divider is engineered to provide excellent amplitude and phase symmetry throughout the operating range, regardless of port selection. Maximum division symmetry is obtained when port 1 is used as input, with ports 2 and 3 providing the divided signal output.
