MHF4-male to SMA-female / Jack Adapter

Adapter for antenna Cable: SMA female to MHF4-male

• See also our MHF4 To SMA cables.
• One end has a MHF4 male connector and the other end has a SMA female straight connector.

Compatibility with wireless applications: This antenna cable adapter's range of frequency band compatibility (from 0 to 18GHz), consistently low broadband VSWR, and impedance matching to 50 Ohm cables, makes them compatible and compliant for all the following applications:

• All WiFi standards: 2.4GHz and 5GHz applications: 802.11AC, 802.11N, 802.11G, 802.11B, 802.11A
• Cellular Wireless LTE / 4G, GSM / 3G WiMAX: Data and voice applications
• IoT wireless, automation & Machine to Machine (M2M): Bluetooth, ZigBee, RFID, LoRa, LTE-m, NB-IoT.

MHF4-male has a pin and is the connector that is the "jack" on devices such as Bluetooth beacons, Printed Circuit Boards (PCBs) and internal mini-PCI wireless cards (even though the gender is male, it is the jack MHF4 connector. MHF4 connectors are widely used in IOT (Internet of Things) applications.

• MHF4 cables have a MHF4 female connector in 95% of cases.

SMA-female connector: Characteristics / Composition:

• SMA is a round screw-type connector, with medium-sized, threaded coupling connectors that are rated for frequencies from the lowest (DC) up to 18GHz.

• SMA female diameter:

  Hex nut accommodates a screw/bolt with 5/16" nominal outer diameter
• In other words, the inside diameter of the hex bolt is 5/16"
• SMA-female requires a 6.5mm hole
• Center Contact: Beryllium Copper, Gold Plated
• Connector Body: Brass, Gold Plated
• Crimp Ferrule: Copper, Nickel Plated
• Insulators: PTFE

• SMA female and male diameter:
• SMA female outside diameter is 5/16" (7.9375mm): Accommodates a hex nut (bulkhead nut) with 5/16" nominal outer diameter
• SMA male inside diameter is 5/16" (7.9375mm) (the inside diameter where the threads are).

• SMA Gender Determination: Key Point
  • SMA gender is counter-intuitive: Please observe picture & note it is correct.
  • The gender is referring to the pins inside--not the threads. SMA male has threads on inside.
  • More details regarding SMA gender determination.

• SMA-Connector Materials Composition:
• Connector Body: Gold Plated Brass
• Center Contact: Beryllium Copper, Gold Plated
• Crimp Ferrule: Copper, Nickel Plated
• Insulators: PTFE
• Precision machined for low loss in ISO 9001 facilities

Insertion loss: 0.26 dB maximum

• Other SMA Characteristics and Key Points
• SMA female connector is also called "jack" and SMA-male is also called "plug."
• We offer an SMA wrench to assist in installing antennas, cables and adapters with SMA or RP-SMA connector(s).
• SMA-female connector fits items that have an SMA-male connector.
• SMA is a round screw-type connector, with medium-sized, threaded coupling connectors that are rated for frequencies from the lowest (DC) up to 18GHz.

Our MHF4 to SMA adapters are precision machined and gold plated for low signal loss.
