UFL RF Connector PCB Mount Coax Terminal IPEX RF Connector

Description

What is an RF Connector UFL PCB Mount Coax Terminal IPEX RF Connector?

IPEX RF Connector was originally a connector company but was merged by Daiichi Seiko.

IPX, IPEX, UFL, and HSC should all be the same kind of connector, generally called IPEX or IPX, but different manufacturers have their own series and names, such as Daiichi Seiko DAI-ICHI SHIKO called IPEX, Hirose Electric HIROSE UFL And WFL, Murata Murata has HSC.

However, many manufacturers do not have their own names, and will directly label their products as IPEX or UFL connectors.

Mainly used in miniature radio frequency coaxial cable connectors, the package is small, the working frequency is generally 0~6GHz, and common in WiFi antennas, router antennas, GPS antennas, mobile phone antennas, antenna extenders, PCB mounts, coax terminals, etc.

IPEX connectors have different models: MHF, MHF2, MHF3, MHF4, MHF5, etc. There is not much difference in use, the main difference lies in the size (MHF>MHF2>MHF3>MHF4》MHF5). For specific packages, please refer to the manuals of different manufacturers.

The IPEX RF Connector Chart – C&T RF Antennas IncDifferent manufacturers have different models, and the corresponding sockets and plugs have different material numbers, so you need to recognize them when you buy them.

Take the IPEX RF Connector series as an example:

The IPEX RF Connector (Known by a variety of names including AMC, UMCC, IPX, MHF, U.FL).

IPEX/U.FL is good up to 6GHz and is usually used in applications where nothing else would fit. Often times they’re used in laptop Wi-Fi cards and embedded systems.

U.FL Connectors: Ultra Small Surface Mount Coaxial Connectors

Male U.FL connectors are surface-mount parts soldered directly into the host. Female connectors are usually manufactured as a cable assemblies with a high-quality 1.32mm doubly shielded cable.

Female U.FL connectors rely on pressure from the shape of the connector to keep it secure. This does form a very tight ‘snap-in’ connection. As a result, female U.FL connectors will wear out after several connections and will need to be replaced as they aren’t generally intended to be connected and disconnected multiple times.

Female U.FL connectors are not designed with reconnection in mind, and they are only rated for a few reconnects (approximately 30 mating cycles) before replacement is needed. The female U.FL connectors are generally not sold separately, but rather as part of a pigtail with a high-quality 1.32 mm doubly shielded cable, which allows for a low-loss connection.

The male connectors are surface-mounted and soldered directly to the printed circuit board. They are designed to have a characteristic impedance of 50 ohms. The mated connection is only 2.5 mm high and takes as little as 9 mm2 of board space.

The cable-mount, right-angle plug is only available terminated either as a complete cable assembly or pigtail assembly. The connector assembly can be used in conjunction with our surface-mount PCB jacks, which are available in tape-and-reel packaging. Various RF connector interfaces are available as part of the micro-coaxial complete assembly.

 

The difference between the ceramic antenna PCB antenna and IPEX antenna

A ceramic antenna is a miniaturized antenna suitable for Bluetooth devices. Ceramic antennas are divided into bulk ceramic antennas and multilayer ceramic antennas.

The block antenna uses high temperature to sinter the whole ceramic body at one time, and then print the metal part of the antenna on the surface of the ceramic block. The firing of multilayer antennas adopts low-temperature co-firing. The multilayer ceramics are laminated and aligned and then sintered at high temperatures.

Therefore, the metal conductor of the antenna can be printed on each ceramic dielectric layer according to the design needs, which can be effective. Reduce the size of the antenna and achieve the purpose of hiding the antenna.

Since the dielectric constant of the ceramic itself is higher than that of the PCB circuit board, the use of ceramic antennas can effectively reduce the size of the antenna.

The PCB antenna refers to the part on the PCB for wireless reception and transmission.

When transmitting, it converts the high-frequency current of the transmitter into electromagnetic waves in space; when receiving, it converts the electromagnetic waves obtained from space into high-frequency current and input into the receiver.

Its advantages are less space occupancy, low cost, no need to assemble the antenna separately, not easy to touch and damage, and easy assembly of the whole machine, but at a cost — sacrificing performance.

The disadvantages are difficulty for a single antenna field to be rounded, high insertion loss, relatively low efficiency, and ease of being interfered with by the motherboard.

IPEX antenna is an interface between a radio frequency circuit and antenna, which is widely used in wireless local area network (WLAN) related product single board.

Its advantages are field type can be controlled better, insertion loss is low, signal directionality is good, high efficient, has strong anti-interference ability, can reduce the interference on the motherboard, and does not require too much debugging and matching, as terminal manufacturing Or, you only need to connect an IPEX antenna outside;

Of course, there are drawbacks: the cost is high and it is more troublesome to assemble.
