Ducommun

Ducommun's products include very broad ferrite device selections to cover 100 MHz to 110 GHz operation frequency range. These devices include narrow band drop-in (FID and FCD), connectorized (FIC and FCC), junction (FIW and FCW) isolators and circulators and iso-adapters (FII and FCI). The broad bandwidth versions are offered as full band junction isolators and circulators (FIF and FCF) and Faraday isolators (FFF). These devices feature low insertion loss, high isolation and wide operating temperature range. Low cost and volume production versions of these ferrite devices are available per customers’ request.

	FIC	Connectorized Isolators	FIC series narrow band connectorized isolators cover common Radar and wireless communication frequency bands up to 20 GHz. The isolator is an ideal device where the port isolation is required. The connectorized isolators are equipped with either SMA(F) or SMA(M) connectors for ease connections. The low cost FIC series isolators offer very compact sizes that can be easily inserted into the sub-assembly with minimum size increase. While the standard specifications are shown below, the customer ones with wider bandwidth, higher isolation and operation frequency are available.
	FCC	Connectorized Circulators	FCC series narrow band connectorized circulators cover common Radar and wireless communication frequency bands up to 20 GHz. The circulator is commonly used as a duplexer for transceiver subsystems where the transmitter and receiver ports share a single antenna port. The connectorized circulators equipped with either SMA(F) or SMA(M) connectors for ease connections. The low cost FCC series circulators offer very compact sizes that can be easily inserted into the sub-assembly with minimum size increase. While the standard specifications are shown below, the customer ones with wider bandwidth, higher isolation and operation frequency are available.
