Description
The Keysight Technologies, Inc. HMMC-5033 is a MMIC power amplifier designed for use in wireless transmitters that operate within the 17.7 GHz to 32 GHz range. At 28 GHz it provides 26 dBm of output power (P–1 dB) and 18 dB of small-signal gain from a small easy-to-use device. The HMMC-5033 was designed to be driven by the HMMC-5040 (20–40 GHz) or the HMMC-5618 (5.9–20 GHz) MMIC amplifier for linear transmit applications. This device has input and output matching circuitry for use in 50 Ω environments.
Applications
The HMMC-5033 MMIC is a broadband power amplifier designed for use in transmitters that operate in various frequency bands between 17.7 GHz and 32 GHz. It can be attached to the output of the HMMC-5040 (20–40 GHz) or the HMMC-5618 (5.9–20 GHz) MMIC amplifier, increasing the power handling capability of transmitters requiring linear operation.
Biasing and Operation
The recommended DC bias condition for optimum efficiency, performance, and reliability is VD1 = 3.5 volts and VD2 = 5 volts with VGG set for ID1 + ID2 = 700 mA (no connection to VG1). This bias arrangement results in default drain currents ID1 = 240 mA and ID2 = 460 mA.
A single DC gate supply connected to VGG will bias all gain stages. If operation with both VD1 and VD2 at 5 volts is desired, an additional wire bond connection from the VG1 pad to the VGG external bypass chip-capacitor (shorting VG1 to VGG) will balance the currents in each gain stage. VGG (= VG1) can be adjusted for ID1 + ID2 = 700 mA.
Muting can be accomplished by setting VG1 and/or VGG to the pinchoff voltage VP.
An on chip RF output power detector network is provided. The differential voltage between the det-ref and det-out pads can be correlated with the RF power emerging from the RF output port. Bias the diodes at ~200 mA.
The RF ports are AC-coupled at the RF input to the first stage and the RF output of the second stage.
If the output detector is biased using the on-chip optional det-bias network, an external AC-blocking capacitor may be required at the RF output port.
No ground wires are needed since ground connections are made with plated through-holes to the backside of the device.
