Description
The MAMF-011070 is a high power broadband PIN
diode SPDT switch with a 5 V power management
chip designed for 30 MHz to 6 GHz high power
applications.
The device features low insertion loss, high isolation
with low DC power consumption. It has an integrated
bias controller utilizing a boost circuit. This switch
requires only a single 5 V supply, and a single TX /RX control signal that is compatible with 1.8 V or
3.3 V logic.

Switch Biasing Information

Boost Biasing Information

R1 and R2 are used to set the forward bias current(IF) of the TX or the RX series diode. The IF controls
the Insertion Loss of the ANT to TX or ANT to RX
path respectively.
For R1 = R2 = 69.8 Ω the IF = 0.1 A
R1 = R2 = 2 * (VCC - 1.52 V) / IF.
R1 & R2 must meet the following power requirement:
PR1/2 > (0.5 * IF)2 * R1

D1 diode requirements: VB = 40 V, Forward Current= 200 mA, Forward Surge Current = 750 mA

R3 and R4 are used to set the forward bias current(IFShD) in the RX shunt diode of the switch. The IFShD
controls the RX isolation.
For R3 = R4 = 3.6 kΩ the IFShD = 0.01 A
R3 = R4 = 2* (18 V) / IF
These resistors must meet the following power
requirement: PR3/4 > (0.5 * IFShD)2 * R3During boost period, VUREC (Pin 15) transient peakvoltage and current can be as high as 24 V and750 mA. Use recommend components from Parts
List for proper current handling.
R7 and R8 are a resistive divider used to set theboost voltage. Use recommended components fromParts List for proper boost performance.
