SP1T Pin Diode Switches
Absorptive and Reflective
Pulsar Microwave manufactures pin diode RF switches that are controlled by TTL logic. This configuration is known as single pole, single throw and is often abbreviated SPST or SP1T. They have been engineered to function in 50-ohm systems, and are designed to operate from 40 MHz to 18 GHz. They have a switching time of 100 nanoseconds and input power rating of 200 mW (23 dBm). Performance of 1.6:1 or better VSWR and minimum isolation of 60 dB is typical of most models. All switches of this type require both +5VDC and -5VDC to operate.
Typical current consumption is +/- 30 mA. TTL control logic of 0 to +5VDC is required. Units comes standard with SMA connectors.
SP2T Pin Diode Switches
Absorptive and Reflective
Pulsar Microwave's 2-way switches are available in absorptive and reflective designs from 20 MHz to 18 GHz. They are also referred to as single pole, double throw and abbreviated SPDT or SP2T. These switches have a typical VSWR performance of 1.6:1 or better and input power handling of 200 milliwatts maximum. Switching time is 100 nanoseconds, and isolation of 60 dB or greater for most models..
Supply voltages are +5V and -5V, with TTL logic control voltage of 0 to 5 volts. Both absorptive and reflective SPDT switches are packaged into Pulsar Microwave's SW2 outline. Configuration is standard with SMA female connectors. Voltage is applied with wire wrap feed thru terminals. The housing serves as electrical ground, and two turret terminals are installed for wiring
SP3T Pin Diode Switches
Absorptive and Reflective
Pulsar Microwave manufactures 3-way absorptive and reflective switches for use in 50-ohm systems. These SP3T switches operate from 100 MHz to 18 GHz and handle 200 mW input power. VSWR performance is often 1.6:1 or better with 100 ns switching time.
Minimum isolation of 60 dB is specified for most units. Absorptive and reflective switches require +5V and -5V power supply to function. Control logic is from 0 to +5 volts. All voltage and ground connections are made by feed thru and turret terminals, respectively.
SP4T Pin Diode Switches
Absorptive and Reflective
The 4-way series of absorptive and reflective switches operate from 100 MHz to 16 GHz. They are rated at 200 mW maximum input power and have a switching time of 100 ns. SP4T switches that operate up to 8 GHz have a maximum VSWR of 1.6:1 and minimum isolation of 60 dB.
All absorptive and reflective switches manufactured by Pulsar Microwave require both positive and negative 5-volt supplies. Additionally, the TTL control logic operates from 0 to +5 VDC. Voltage connection is made with feed thru terminals. Ground connection is made through the chassis and turret terminals.
SP5T Pin Diode Switches
Absorptive and Reflective
Pulsar Microwave's 5-way RF switches cover bands from 300 MHz to 12 GHz in both absorptive and reflective configuration. These SP5T switches have a rating of 200 mW maximum input power and a switching time of 100 ns. They are specified with a minimum isolation of 60 dB and most models maintain a VSWR of 1.6:1 or better on all ports.
The SP5T switches are driven by TTL logic control circuitry and require both positive and negative 5-volt supplies for operation. A 9-pin D-SUB connector provides the interface for the power and logic voltages.
SP6T Pin Diode Switches
Absorptive and Reflective
The SP6T series of 6-way absorptive and reflective switches manufactured by Pulsar Microwave cover applications from 300 MHz to 12 GHz. They have an isolation of 60 decibels and most models specify 1.6:1 or better return loss throughout frequency band.
These 6-way switches require a +/- 5VDC supply to operate. Switching control uses individual 0-5V TTL control logic. Voltage and logic control interfaces into a system using a 9-pin D-SUB connector installed.
SP8T Pin Diode Switches
Absorptive and Reflective
Pulsar Microwave manufactures 8-way absorptive and reflective RF switches in single-pole 8-throw configuration. They fulfill broadband and narrowband requirements from 40 MHz to 12 GHz and handle 200 milliwatts input power. The SP8T switches have an isolation of 60 dB and switching time of 100 ns. Most models specify 1.6:1 or better VSWR at all ports.
The SP8T switches operate on a power supply of +/- 5VDC and switching control is 0-5 TTL logic. The unit comes standard with SMA female connectors. Options for control are line drivers and decoders.
SP16T Pin Diode Switches
Pulsar Microwave's 16-way switches cover 500 MHz to 10 GHz in single pole, 16-throw configuration. Maximum input power is 200 mW and switching time is 100 ns. SMA female connectors are standard. A 15-pin D-SUB male connector makes the internal connections to the power, ground and logic circuitry. Switching control is TTL with the option of line drivers and decoders.
